09.30.2016 - ppc64el packages now available on apt.postgresql.org



View PostgreSQL-Press related news.

PostgreSQL's repository for Debian and Ubuntu packages, apt.postgresql.org, has been extended to provide pre-built binary packages for a third architecture. ppc64el, the little-endian incarnation of IBM's POWER architecture, is joining the existing amd64 (64-bit x86 Intel) and i386 (32-bit x86 Intel) architectures.

The PostgreSQL 9.6 release is already included in the repository.

Just as on the existing architectures, all packages will be supported for all PostgreSQL major releases - which is currently all releases from 9.1 to 9.6. With only a few exceptions, all packages previously included in the repository have been compiled for ppc64el. [1]

Supported Debian distributions are Debian 8 (Jessie) and unstable (Sid); supported Ubuntu releases are 14.04 (Trusty) and 16.04 (Xenial).

This initiative has been led by 2ndQuadrant in cooperation with IBM Italy. Thanks must also be given to credativ for helping with the setup of the build infrastructure for the ppc64el architecture.

The ppc64el build host is provided by IBM Power Systems Linux Center - Montpellier.

Kind Regards, Marco / Debian PostgreSQL Maintainers

[1] pg-partman is not available for 9.6 yet; psqlodbc and libpqtypes are not available on Trusty.

09.29.2016 - pgAdmin 4 v1.0 Released!



View PostgreSQL-Press related news.

The pgAdmin Development Team are pleased to announce the release of pgAdmin 4 version 1.0.

pgAdmin is the leading Open Source management and administration tool for PostgreSQL.

pgAdmin 4 is a complete rewrite of pgAdmin, built using Python and Javascript/jQuery. A desktop runtime written in C++ with Qt allows it to run standalone for individual users, or the web application code may be deployed directly on a webserver for use by one or more users through their web browser. The software has the look and feel of a desktop application whatever the runtime environment, and vastly improves on pgAdmin III with updated user interface elements, multi-user/web deployment options, dashboards and a more modern design.

The application was designed as a pluggable framework that can easily be extended with plugin modules to provide additional functionality to support other software in the PostgreSQL ecosystem, or functionality of forks of PostgreSQL.

For more information, screenshots, documentation and downloads, please see the website at:

https://www.pgadmin.org/

pgAdmin 4 is also bundled in the PostgreSQL 9.6 installers from EDB at:

http://www.enterprisedb.com/products-services-training/pgdownload

I'd like to take this opportunity to thank all those involved in the design, implementation, testing and documentation of pgAdmin 4, estimated at well over 10,000 hours of effort over the last year. For more information about the project, please see the blog post at:

http://pgsnake.blogspot.co.uk/2016/04/pgadmin-4-elephant-nears-finish-line.html

Finally, I'd like to thank the management at EDB for supporting this project and allowing me to enlist the efforts of over 15 employees from multiple teams. Without their support pgAdmin 4 would not exist today.

Dave Page, pgAdmin Project Lead

09.29.2016 - PostgreSQL 9.6 Released!



View PostgreSQL-Press related news.

PostgreSQL 9.6, the latest version of the world's leading open source database, was released today by the PostgreSQL Global Development Group. This release will allow users to both scale up and scale out high performance database workloads. New features include parallel query, synchronous replication improvements, phrase search, and improvements to performance and usability, as well as many more features.

Scale Up with Parallel Query

Version 9.6 adds support for parallelizing some query operations, enabling utilization of several or all of the cores on a server to return query results faster. This release includes parallel sequential (table) scan, aggregation, and joins. Depending on details and available cores, parallelism can speed up big data queries by as much as 32 times faster.

"I migrated our entire genomics data platform - all 25 billion legacy MySQL rows of it - to a single Postgres database, leveraging the row compression abilities of the JSONB datatype, and the excellent GIN, BRIN, and B-tree indexing modes. Now with version 9.6, I expect to harness the parallel query functionality to allow even greater scalability for queries against our rather large tables," said Mike Sofen, Chief Database Architect, Synthetic Genomics.

Scale Out with Synchronous Replication and postgres_fdw

Two new options have been added to PostgreSQL's synchronous replication feature which allow it to be used to maintain consistent reads across database clusters. First, it now allows configuring groups of synchronous replicas. Second, the "remote_apply" mode creates a more consistent view of data across multiple nodes. These features support using built-in replication to maintain a set of "identical" nodes for load-balancing read workloads.

The PostgreSQL-to-PostgreSQL data federation driver, postgres_fdw, has new capabilities to execute work on remote servers. By "pushing down" sorts, joins, and batch data updates, users can distribute workload across multiple PostgreSQL servers. These features should soon be added to other FDW drivers.

"With the capabilities of remote JOIN, UPDATE and DELETE, Foreign Data Wrappers are now a complete solution for sharing data between other databases and PostgreSQL. For example, PostgreSQL can be used to handle data input going to two or more different kinds of databases," said Julyanto Sutandang, Director of Business Solutions at Equnix.

Better Text Search with Phrases

PostgreSQL's full text search feature now supports "phrase search." This lets users search for exact phrases, or for words within a specified proximity to each other, using fast GIN indexes. Combined with new features for fine-tuning text search options, PostgreSQL is the superior option for "hybrid search" which puts together relational, JSON, and full text searching.

Smoother, Faster, and Easier to Use

Thanks to feedback and testing by PostgreSQL users with high-volume production databases, the project has been able to improve many aspects of performance and usability in this release. Replication, aggregation, indexing, sorting, and stored procedures have all been made more efficient, and PostgreSQL now makes better use of resources with recent Linux kernels. Administration overhead for large tables and complex workloads was also reduced, especially through improvements to VACUUM.

Other Features

Version 9.6 has many other features added over the last year of development, among them:

  • New system views and functions: pg_stat_wal_receiver, pg_visibility, pg_config, pg_blocking_pids, pg_notification_queue_usage
  • Command progress reporting support
  • Cascade support for installing extensions
  • pg_basebackup concurrency and replication slot support
  • Wait Event support
  • View editing and crosstabs in psql
  • User-defined expiration for old snapshots
  • Index-only scans for partial indexes

Additionally, the project has changed and improved the API for binary hot backups. As such, developers of custom backup software for PostgreSQL should do additional testing around the new version. See the Release Notes for more detail.

09.27.2016 - Barman 2.0 Released



View PostgreSQL-Press related news.

Barman (Backup and Recovery Manager) is an open-source administration tool for disaster recovery of PostgreSQL servers written in Python. Barman enables the remote online hot backup of multiple servers in business critical environments, helping make a DBA's life easier during the recovery stage - now with zero data loss.

What's New

The major release of version 2.0 is an important milestone in Barman's journey as it introduces support for a “streaming only” backup of a PostgreSQL server, removing the need for SSH connections altogether.

This is made possible by two significant improvements related to streaming replication:

  • Transparent integration with pg_basebackup for backup operations
  • Full support of replication slots for WAL streaming

Through streaming-only backups, Barman is now able to reach Docker and Windows users of PostgreSQL. From an architectural point of view, Barman is now able to offer even more versatility and flexibility by combining traditional SSH communications with PostgreSQL’s native streaming connections.

Another important addition is support for synchronous WAL streaming that allows zero data loss backups and reduces implementation costs of PostgreSQL clusters with “RPO=0” business continuity requirements.

Barman 2.0 also supports the new concurrent backup API introduced in PostgreSQL 9.6, eliminating the need for the pgespresso extension when taking backups from a standby server.

The new 'barman-cli' package improves integration of Barman with repmgr for better high availability outcomes.

Disaster Recovery

Recovery planning is frequently overlooked during business continuity planning, but failure is always an option. Unfortunately, our experience has shown us that typically, disaster recovery plans are only implemented after suffering severe data loss or down-time. Business critical environments must be prepared for the unexpected and Barman is the right tool organisations can use to be prepared.

Now, through synchronous WAL streaming, Barman allows a Recovery Point Objective (RPO) of 0. Barman now also supports PostgreSQL on Windows (experimental) and Docker. Improved support of very large databases and clusters is currently being developed for a future Barman release.

Professional Support for Barman

In addition to the disaster recovery and business continuity support already available through 2ndQuadrant, as the developers of Barman, the team at 2ndQuadrant provides superior support for Barman users. The turnkey disaster recovery solution service includes architecture analysis, installation, training and a final simulation with internal personnel. 2ndQuadrant offers custom solutions, development of new features, training, and 24/7 production support.

Upgrading from Barman 1.X

The 2.0 release requires that users explicitly configure their archiving strategy. Before, the file based archiver controlled by the ‘archiver’ option was enabled by default. When you upgrade your Barman installation to 2.0, make sure you add the appropriate line globally or for any server that requires it. Barman using officially distributed RPM and Debian packages will be automatically updated.

For installation or upgrade instructions, please see the "Links" section below.

For the comprehensive release notes, please read "Barman 2.0 Release Notes".

If you have any questions about Barman and disaster recovery scenarios using Barman, you can reach the dev team using the community mailing list.

To submit private inquiries regarding implementation, customised features or sponsorship opportunities email the team directly at info@pgbarman.org.

09.22.2016 - Announcement: Amazon RDS for PostgreSQL Enhancements: Support for new minor versions, Logical Replication, and Amazon RDS PostgreSQL as a source for AWS DMS



View PostgreSQL-Press related news.

Starting today, you can take advantage of several new enhancements to Amazon RDS for PostgreSQL. These include new minor versions (9.3.14, 9.4.9 and 9.5.2), support for logical replication, event triggers, and the ability to use RDS for PostgreSQL as a source for AWS Database Migration Service.

New Minor Versions:

Customers can now launch new and upgrade their existing Amazon RDS for PostgreSQL instances to new PostgreSQL minor versions 9.3.14, 9.4.9, and 9.5.4, using either the AWS console or Amazon RDS API. These new minor version releases contain several enhancements and fixes to PostgreSQL. To learn more about these new versions, please refer to their release notes:

Release Notes for 9.3.14

Release Notes for 9.4.9

Release Notes for 9.5.4

Logical Replication and support for AWS Database Migration Services

Amazon RDS for PostgreSQL now supports logical replication on RDS for PostgreSQL versions 9.4.9 and 9.5.4. With logical replication, we have added support for logical decoding, and you can setup logical replication slots on your instance and stream changes from the database through these slots. A new rds_replication role, assigned to the master user by default, can be used to grant permissions to manipulate and stream data through logical slots. To enable logical replication, set the parameter rds.logical_replication to 1. These logical slots also enable the RDS for PostgreSQL to be used as a source for AWS Database Migration Service (DMS). You can learn more about using RDS for PostgreSQL as a source for DMS in the AWS Database Blog and RDS documentation.

Event Triggers:

Amazon RDS now supports the event triggers in PostgreSQL versions 9.4.9 and later and version 9.5.4 and later. The master user account can be used to create, modify, rename, and delete event triggers. Event triggers are at the DB instance level, so they apply to all databases on an instance. For more information about event triggers for Amazon RDS for PostgreSQL, refer to the RDS documentation.

New Parameter for RAM Disk Size:

Amazon RDS for PostgreSQL now supports a new parameter, rds.pg_stat_ramdisk_size, which can be used to define the system memory allocated to a RAM disk for storing PostgreSQL stats_temp_directory. Under certain workloads, it can result in improved performance and decreased I/O requirements. You can read about the details of the new parameter here in the RDS documentation.

All the enhancements mentioned above are available in all regions. You can learn more about Amazon RDS for PostgreSQL on the RDS product page and the RDS documentation.

08.11.2016 - Postgres-BDR 9.4 1.0 Released



View PostgreSQL-Press related news.

Oxford, United Kingdom - August 11, 2016

Bi-Directional Replication for PostgreSQL (Postgres-BDR, or BDR) is the first open source multi-master replication system for PostgreSQL to reach full production status, developed by 2ndQuadrant and assisted by a keen user community. BDR is specifically designed for use in geographically distributed clusters, using highly efficient asynchronous logical replication, supporting anything from 2-48 nodes in a distributed database.

WHAT'S NEW?

Significant improvements related to stability and bug fixes have been made in this release. The most important factors of this release are:

  • Smoother handling of schema changes (DDL) statements allowing increased operational stability and reduced maintenance.
  • Various bug fixes for operational issues demonstrating high level of maturity
  • Performance tuning, especially of global sequence handling
  • Removal of the now deprecated UDR
  • Extensive documentation improvements based upon user feedback

For a more comprehensive list of release notes, please click here: http://bdr-project.org/docs/stable/release-1.0.0.html

SUPPORT & RELEASE SCHEDULE

Postgres-BDR 9.4 1.0 will be supported until December 2019, when PostgreSQL 9.4 goes EOL. BDR continues to be developed and BDR9.6 will be released within 6 months. The BDR project has already delivered the majority of its code into PostgreSQL core, though it will likely be about 2-3 more years before this functionality is available in PostgreSQL core.

IS Postgres-BDR RIGHT FOR YOU?

BDR is well suited for databases where:

  • Data is distributed globally
  • Majority of data is written to from only one node at a time (For example, the US node mostly writes changes to US customers, each branch office writes mostly to branch-office-specific data, and so on.)
  • There is a need for SELECTs over complete data set (lookups and consolidation)
  • There are OLTP workloads with many smaller transactions
  • Transactions mostly touching non overlapping sets of data
  • There is partition and latency tolerance

However, this is not a comprehensive list and use cases for BDR can vary based on database type and functionality.

In addition, BDR aids business continuity by providing increased availability during network faults. Applications can be closer to the data and more responsive for users, allowing for a much more satisfying end-user experience.

PROFESSIONAL SUPPORT FOR BDR

BDR is developed and supported by 2ndQuadrant. 2ndQuadrant provides professional support for BDR, as well as consultation and training. With our deep knowledge of distributed databases, we will ensure that you are able to evaluate your use case and applications and determine the most suitable product or solution.

BDR is also available in 2ndQuadrant Cloud, initially on AWS.

For more information, please visit the homepage: https://2ndquadrant.com/en/resources/bdr/.
