05.23.2016 - Barman 1.6.1 released



View PostgreSQL-Press related news.

23 May 2016: 2ndQuadrant is proud to announce the release of Barman version 1.6.1, a Backup and Recovery Manager for PostgreSQL.

This minor release introduces support for '--peek' option for 'get-wal' command which allows users to implement parallel remote restore commands on standby servers and during recovery.

Through the new 'replication-status' command, Barman becomes a very practical tool for monitoring streaming replication status of every managed server.

A few important improvements have been added to the 'check' command, which should make installation and initial configuration easier. Another step in this direction is the 'switch-xlog' command, a new feature also included in this release.

Minor bugs have also been fixed, including support for 'archive_mode=always' for PostgreSQL 9.5, as well as 'FAILED' backups preventing new one from being taken.

Many thanks for funding towards the development of this release go to Jobrapido (www.jobrapido.com), Navionics (www.navionics.com), and Subito.it (www.subito.it).

However, for a complete list of changes, see the "Release Notes" section below.

Links

Release notes

  • Add '--peek' option to 'get-wal' command to discover existing WAL files from the Barman's archive

  • Add 'replication-status' command for monitoring the status of any streaming replication clients connected to the PostgreSQL server. The '--target' option allows users to limit the request to only hot standby servers or WAL streaming clients

  • Add the 'switch-xlog' command to request a switch of a WAL file to the PostgreSQL server. Through the '--force' it issues a 'CHECKPOINT' beforehand

  • Add 'streaming_archiver_name' option, which sets a proper 'application_name' to 'pg_receivexlog' when 'streaming_archiver' is enabled (only for PostgreSQL 9.3 and above)

  • Check for superuser privileges with PostgreSQL's standard connections (#30)

  • Check the WAL archive is never empty

  • Check for 'backup_label' on the master when server is down

  • Improve barman-wal-restore contrib script

  • Bug fixes:

    • Treat the "failed backups" check as non-fatal
    • Rename '-x' option for get-wal as '-z'
    • Add archive_mode=always support for PostgreSQL 9.5 (#32)
    • Properly close PostgreSQL connections when necessary
    • Fix receive-wal for pg_receive_xlog version 9.2

05.13.2016 - PostgreSQL 9.5.3, 9.4.8, 9.3.13, 9.2.17 and 9.1.22 Released!



View PostgreSQL-Press related news.

2016-05-12 Cumulative Bug Fix Release

The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 9.5.3, 9.4.8, 9.3.13, 9.2.17 and 9.1.22. This release fixes a number of issues reported by users over the last two months. Most database administrators should plan to upgrade at the next available downtime, unless they have been affected directly by the fixed issues.

Bug Fixes and Improvements

This update fixes several problems which caused downtime for users, including:

  • Clearing the OpenSSL error queue before OpenSSL calls, preventing errors in SSL connections, particularly when using the Python, Ruby or PHP OpenSSL wrappers
  • Fixed the "failed to build N-way joins" planner error
  • Fixed incorrect handling of equivalence in multilevel nestloop query plans, which could emit rows which didn't match the WHERE clause.
  • Prevented two memory leaks with using GIN indexes, including a potential index corruption risk.

The release also includes many other bug fixes for reported issues, many of which affect all supported versions:

  • Fix corner-case parser failures occurring when operator_precedence_warning is turned on
  • Prevent possible misbehavior of TH, th, and Y,YYY format codes in to_timestamp()
  • Correct dumping of VIEWs and RULEs which use ANY (array) in a subselect
  • Disallow newlines in ALTER SYSTEM parameter values
  • Avoid possible misbehavior after failing to remove a tablespace symlink
  • Fix crash in logical decoding on alignment-picky platforms
  • Avoid repeated requests for feedback from receiver while shutting down walsender
  • Multiple fixes for pg_upgrade
  • Support building with Visual Studio 2015

This update also contains tzdata release 2016d, with updates for Russia, Venezuela, Kirov, and Tomsk.

Updating

All PostgreSQL update releases are cumulative. As with other minor releases, users are not required to dump and reload their database or use pg_upgrade in order to apply this update release; you may simply shut down PostgreSQL and update its binaries. Users who have skipped one or more update releases may need to run additional, post-update steps; please see the release notes for earlier versions for details.

05.12.2016 - PostgreSQL 9.6 Beta 1 Released



View PostgreSQL-Press related news.

The PostgreSQL Global Development Group announces today that the first beta release of PostgreSQL 9.6 is available for download. This release contains previews of all of the features which will be available in the final release of version 9.6, although some details will change before then. Users are encouraged to begin testing their applications against this latest release.

Major Features of 9.6

Version 9.6 includes significant changes and exciting enhancements including:

  • Parallel sequential scans, joins and aggregates
  • Support for consistent, read-scaling clusters through multiple synchronous standbys and "remote_apply" synchronous commit.
  • Full text search for phrases
  • postgres_fdw can now execute sorts, joins, UPDATEs and DELETEs on the remote server
  • Decreased autovacuum impact on big tables by avoiding "refreezing" old data.

In particular, parallel execution should bring a noticeable increase in performance to supported queries.

Help Test for Bugs

As with other major releases, the improvements in PostgreSQL include changes to large amounts of code. We count on you to test the altered version with your workloads and testing tools in order to find bugs and regressions before the release of PostgreSQL 9.6.0. In addition to testing that the new features work as documented, consider testing the following:

  • Do parallel queries actually improve performance for you?
  • Can you make parallel queries crash or lose data?
  • Do our code changes cause PostgreSQL to not function on your platform?
  • Does improved vacuum freezing safely reduce autovacuum of large tables?
  • Does phrase search return the results you expect?

Version 9.6 Beta 1 also makes changes to the binary backup API. Administrators should test version 9.6 with PostgreSQL backup tools, including pgBackRest, Barman, WAL-E, and other packaged and in-house software.

As this is a Beta, minor changes to database behaviors, feature details, and APIs are still possible. Your feedback and testing will help determine the final tweaks on the new features, so test soon. The quality of user testing helps determine when we can make a final release.

Beta Schedule

This is the first beta release of version 9.6. The PostgreSQL Project will release additional betas as required for testing, followed by one or more release candidates, until the final release in late 2016. For further information please see the Beta Testing page.

04.19.2016 - Postgres-XL 9.5 R1 Released!



View PostgreSQL-Press related news.

The Postgres-XL community is pleased to announce the 1st release of Postgres-XL 9.5. This release has been fully synced up till PostgreSQL 9.5.2.

Postgres-XL is a massively parallel database built on top of, and very closely compatible with PostgreSQL 9.5 and its set of advanced features. Postgres-XL is fully open source and many parts of it will feed back directly or indirectly into later releases of PostgreSQL, as we begin to move towards a fully parallel sharded version of core PostgreSQL.

Postgres-XL is different because it supports both Business Intelligence and OLTP workloads in the same horizontally scalable server. This allows Postgres-XL to support a diverse range of workloads

  • OLTP workloads that need write-scalability as well as read-scalability
  • Business Intelligence requiring OLAP with massive parallelism
  • Operational Data Store/ Central Data Backbone
  • Distributed Key-Value store using JSONB, similar to NoSQL
  • Internet of Things applications
  • Mixed-workload environments

Star schema style SQL queries exhibit large performance gains from massively parallel processing (MPP). Many queries show fully linear performance gains, for example a 16-node XL cluster is 16 times faster than PostgreSQL on one node. Postgres-XL is able to successfully complete the complex TPC-H business intelligence benchmark, showing its capability to address much more than basic operations.

Besides proving its mettle on Business Intelligence workloads, Postgres-XL has performed remarkably well on OLTP workloads when running pgBench (based on TPC-B) benchmark. In a 4-Node (Scale: 4000) configuration, compared to PostgreSQL, XL gives up to 230% higher TPS (-70% latency comparison) for SELECT workloads and up to 130% (-56% latency comparison) for UPDATE workloads. Yet, it can scale much, much higher than even the largest single node server.

Postgres-XL’s High Availability functionality has also been enhanced in this release. Popular features such as BRIN indexes, JSONB and GIN index compression are fully supported, as are many popular extensions.

Postgres-XL is available for download here: www.postgres-xl.org/download/ You can go through XL’s comprehensive documentation here: files.postgres-xl.org/documentation/

We expect R2 to bring further features to Postgres-XL 9.5 in the next few months.

2ndQuadrant has led the development of Postgres-XL 9.5, building upon the work of many others over a long period of continuous development, with easily more than 10 man years of development. After six months of professional formal alpha-level testing & tuning, and an additional 2 months in Beta phase with user feedback, the project has now reached the next stage of maturity and we are now ready to release it for production use.

The research leading to these results has received funding from the European Union’s Seventh Framework Programme (FP7/2007-2015) under grant agreement n° 318633. Postgres-XL has also received support and assistance from European Space Agency's Gaia project, as well as other users in industry.

04.17.2016 - pgBackRest 1.0 Released



View PostgreSQL-Press related news.

April 17, 2016: Crunchy Data is proud to announce pgBackRest 1.0, Reliable PostgreSQL Backup & Restore.

Release 1.0

The first stable of release of pgBackRest introduces a new, more capable repository format, simpler configuration, and comprehensive support for backup and restore of symlinked directories and files.

There are a number of important changes in pgBackRest 1.0 so be sure to read the release notes very carefully before upgrading.

Links

Features

Multithreaded Backup & Restore

Compression is usually the bottleneck during backup operations but, even with now ubiquitous multi-core servers, most database backup solutions are still single-threaded. pgBackRest solves the compression bottleneck with multithreading.

Utilizing multiple cores for compression makes it possible to achieve 1TB/hr raw throughput even on a 1Gb/s link. More cores and a larger pipe lead to even higher throughput.

Local or Remote Operation

A custom protocol allows pgBackRest to backup, restore, and archive locally or remotely via SSH with minimal configuration. An interface to query PostgreSQL is also provided via the protocol layer so that remote access to PostgreSQL is never required, which enhances security.

Full, Incremental, & Differential Backups

Full, differential, and incremental backups are supported. pgBackRest is not susceptible to the time resolution issues of rsync, making differential and incremental backups completely safe.

Backup Rotation & Archive Expiration

Retention polices can be set for full and differential backups to create coverage for any timeframe. WAL archive can be maintained for all backups or strictly for the most recent backups. In the latter case WAL required to make older backups consistent will be maintained in the archive.

Backup Integrity

Checksums are calculated for every file in the backup and rechecked during a restore. After a backup finishes copying files, it waits until every WAL segment required to make the backup consistent reaches the repository.

Backups in the repository are stored in the same format as a standard PostgreSQL cluster (including tablespaces). If compression is disabled and hard links are enabled it is possible to snapshot a backup in the repository and bring up a PostgreSQL cluster directly on the snapshot. This is advantageous for terabyte-scale databases that are time consuming to restore in the traditional way.

All operations utilize file and directory level fsync to ensure durability.

Backup Resume

An aborted backup can be resumed from the point where it was stopped. Files that were already copied are compared with the checksums in the manifest to ensure integrity. Since this operation can take place entirely on the backup server, it reduces load on the database server and saves time since checksum calculation is faster than compressing and retransmitting data.

Streaming Compression & Checksums

Compression and checksum calculations are performed in stream while files are being copied to the repository, whether the repository is located locally or remotely.

If the repository is on a backup server, compression is performed on the database server and files are transmitted in a compressed format and simply stored on the backup server. When compression is disabled a lower level of compression is utilized to make efficient use of available bandwidth while keeping CPU cost to a minimum.

Delta Restore

The manifest contains checksums for every file in the backup so that during a restore it is possible to use these checksums to speed processing enormously. On a delta restore any files not present in the backup are first removed and then checksums are taken for the remaining files. Files that match the backup are left in place and the rest of the files are restored as usual. Since this process is multithreaded, it can lead to a dramatic reduction in restore times.

Advanced Archiving

Dedicated commands are included for both pushing WAL to the archive and retrieving WAL from the archive.

The push command automatically detects WAL segments that are pushed multiple times and de-duplicates when the segment is identical, otherwise an error is raised. The push and get commands both ensure that the database and repository match by comparing PostgreSQL versions and system identifiers. This precludes the possibility of misconfiguring the WAL archive location.

Asynchronous archiving allows compression and transfer to be offloaded to another process which maintains a continuous connection to the remote server, improving throughput significantly. This can be a critical feature for databases with extremely high write volume.

Tablespace & Link Support

Tablespaces are fully supported and on restore tablespaces can be remapped to any location. It is also possible to remap all tablespaces to one location with a single command which is useful for development restores.

File and directory links are supported for any file or directory in the PostgreSQL cluster. When restoring it is possible to restore all links to their original locations, remap some or all links, or restore some or all links as normal files or directories within the cluster directory.

Compatibility with PostgreSQL >= 8.3

pgBackRest includes support for versions down to 8.3, since older versions of PostgreSQL are still regularly utilized.

About

pgBackRest aims to be a simple, reliable backup and restore system that can seamlessly scale up to the largest databases and workloads. Instead of relying on traditional backup tools like tar and rsync, pgBackRest implements all backup features internally and uses a custom protocol for communicating with remote systems. Removing reliance on tar and rsync allows for better solutions to database-specific backup challenges. The custom remote protocol allows for more flexibility and limits the types of connections that are required to perform a backup which increases security.

Crunchy Data supports the ongoing and active development of pgBackRest as an entirely open source project, released under the BSD-compatible MIT license.

04.15.2016 - Amazon RDS for PostgreSQL now supports PostgreSQL 9.5



View PostgreSQL-Press related news.

April 8, 2016 – Amazon RDS for PostgreSQL now supports major version 9.5, which contains several new features including UPSERT capability, Row Level Security (RLS) and several Big Data capabilities. In addition to supporting the new major version of PostgreSQL, 9.5, RDS for PostgreSQL also supports new minor versions 9.4.7 and 9.3.12, which contain several enhancements and fixes. All three versions are available to use starting today.

PostgreSQL 9.5 (supported via minor version 9.5.2) offers the following new features:

UPSERT: Shorthand for "INSERT, ON CONFLICT UPDATE", this feature allows new and updated rows to be treated the same way, enabling the database to handle conflicts between concurrent data changes and simplifying application development. Row Level Security (RLS): RLS implements true per-row and per-column data access control which integrates with external label-based security stacks, giving you more control over securing your data. Big Data features: PostgreSQL 9.5 includes multiple new features for integrating with Big Data systems, including BRIN Indexing to create tiny but effective indexes for "naturally ordered" tables; faster sorts using "abbreviated keys" algorithm to sort through text and NUMERIC fields faster; CUBE, ROLLUP and GROUPING SETS to produce reports with multiple levels of summarization to allow integration with OLAP tools such as Tableau; Foreign Data Wrappers (FDWs) with IMPORT FOREIGN SCHEMA and JOIN pushdown to make query connections to external databases easier and more efficient; and TABLESPACE to generate a statistical sample of huge tables to avoid expensive sorting. You can create a new PostgreSQL 9.5.2 database instance with a few clicks on the AWS Management Console (learn how). You may also upgrade an existing PostgreSQL 9.4 instance to version 9.5.2 using major version upgrade. If you wish to upgrade from version 9.3 to 9.5, you will have to perform point-and-click upgrade twice. Each upgrade operation involves a short period of unavailability for your database instance. Learn more about upgrading your database instances.

In addition to PostgreSQL 9.5.2, we also now support PostgreSQL 9.4.7 and 9.3.12, which include several fixes and enhancements as listed here. To learn more about these new versions, please refer to their release notes:

Release Notes for 9.5.2

Release Notes for 9.4.7

Release Notes for 9.3.12

All three versions also now provide visibility into the status of autovacuum by allowing rds_superuser access to autovacuum sessions in pg_stat_activity. Read more about the new features in PostgreSQL 9.5 on the PostgreSQL website. For more details on using Amazon RDS for PostgreSQL, please refer to the Amazon RDS User's Guide.

The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 9.5.2, 9.4.7, 9.3.12, 9.2.16, and 9.1.21. This release fixes two security issues and one index corruption issue in version 9.5. It also contains a variety of bug fixes for earlier versions. Users of PostgreSQL 9.5.0 or 9.5.1 should update as soon as possible.

Security Fixes for RLS, BRIN

This release closes security hole CVE-2016-2193, where a query plan might get reused for more than one ROLE in the same session. This could cause the wrong set of Row Level Security (RLS) policies to be used for the query.

The update also fixes CVE-2016-3065, a server crash bug triggered by using pageinspect with BRIN index pages. Since an attacker might be able to expose a few bytes of server memory, this crash is being treated as a security issue.

Abbreviated Keys and Corrupt Indexes

In this release, the PostgreSQL Project has been forced to disable 9.5's Abbreviated Keys performance feature for many indexes due to reports of index corruption. This may affect any B-tree indexes on TEXT, VARCHAR, and CHAR columns which are not in "C" locale. Indexes in other locales will lose the performance benefits of the feature, and should be REINDEXed in case of existing index corruption. The feature may be re-enabled in future versions if the project finds a solution for the problem. See the release notes, and the wiki page on this issue for more information.

Other Fixes and Improvements

In addition to the above, many other issues were patched in this release based on bugs reported by our users over the last few months. This includes bugs which affect multiple versions of PostgreSQL, such as:

  • Fix two bugs in indexed ROW() comparisons
  • Avoid data loss due to renaming files
  • Prevent an error in rechecking rows in SELECT FOR UPDATE/SHARE
  • Fix bugs in multiple json_ and jsonb_ functions
  • Log lock waits for INSERT ON CONFLICT correctly
  • Ignore recovery_min_apply_delay until reaching a consistent state
  • Fix issue with pg_subtrans XID wraparound
  • Fix assorted bugs in Logical Decoding
  • Fix planner error with nested security barrier views
  • Prevent memory leak in GIN indexes
  • Fix two issues with ispell dictionaries
  • Avoid a crash on old Windows versions
  • Skip creating an erroneous delete script in pg_upgrade
  • Correctly translate empty arrays into PL/Perl
  • Make PL/Python cope with identifier names

This update also contains tzdata release 2016c, with updates for Azerbaijan, Chile, Haiti, Palestine, and Russia, and historical fixes for other regions.

Updating

Users of version 9.5 will want to REINDEX any indexes they created on character columns in non-C locales. Users of other versions who have skipped multiple update releases may need to perform additional post-update steps; see the Release Notes for details.

All PostgreSQL update releases are cumulative. As with other minor releases, users are not required to dump and reload their database or use pg_upgrade in order to apply this update release; you may simply shut down PostgreSQL and update its binaries.

03.29.2016 - PL/Java 1.5.0 announced; security note.



View PostgreSQL-Press related news.

PL/Java brings functions, triggers, and types in Java. 1.5.0 supports latest PostgreSQL and Java versions with a range of improvements and fixes.

Project site: http://tada.github.io/pljava/
Release notes: http://tada.github.io/pljava/releasenotes.html

Security note:

Several security issues are addressed in PL/Java 1.5.0, as described in the release notes, so sites running earlier versions are encouraged to update. The release notes also describe practical mitigations to reduce risk until an update can be completed.

Platforms:

PL/Java 1.5.0 works with Java 8, 7, or 6 and all 9.x PostgreSQL versions as well as 8.4. To support projects based on older PostgreSQL forks, PL/Java 1.5.0 is also intended to build with 8.3 and 8.2, but has not been tested on those versions.

PL/Java 1.5.0 resolves reported build issues on several platforms, and new sections of the build documentation specifically cover Mac OS X, Solaris, Ubuntu, and Windows (using Visual Studio or MinGW-64). FreeBSD 10.2 or later is expected to work but has not been tested.

Changes:

PL/Java 1.5.0 brings more complete, usable, and documented capability for Java-implemented user-defined base types, composite types, and mirrors of existing PostgreSQL types, an annotation-driven SQL generator reducing the effort of writing deployment SQL by hand, and many smaller improvements and fixes detailed in the release notes. The supplied examples cover many of these features.

Availability:

PL/Java 1.5.0 is available from GitHub as a source release, which builds quickly using Maven:

Release page: https://github.com/tada/pljava/releases/tag/V1_5_0

This wiki page will add links to prebuilt packages that become available.

Many thanks to all the individuals and organizations listed in the release notes under Credits.
