03.04.2015 - Meet the PostgresDAC v3.0.0



View PostgreSQL-Press related news.

We've released our new major version of PostgresDAC component suite. It’s been a long way started almost two years ago. The goals were complicated, and not all of them were accomplished. However, in general we may proudly say without a doubt that this release is a significant milestone.

Dump and restore functionality

TPSQLDump and TPSQLRestore components is a pair that is one of a kind on the whole market. There are no more such facilities not only in the Delphi or C Builder world, but for any other IDE's or toolchains. That is why our first goal was to keep this classes up to date. A huge amount of work was done and a year ago the brand new v3 TPSQLDump and TPSQLRestore components were published as part of v2.11.0 release.

TPSQLDump and TPSQLRestore are fully compatible with native pg_dump and pg_restore utilities. Each and every native feature is supported out of the box:

  • output formats (binary, text, directory, gzipped),
  • parallel dumping and restoring,
  • comprehensive selection, filtering and reordering of archived items,
  • SQL-92 specific output options, etc.

Asynchronous Fetch-On-Demand mode

The default TPSQLQuery's mode is suitable for submitting commands and getting result sets in normal, synchronous applications. However, there are few drawbacks, that may be of importance to developers:

  • TPSQLQuery.Open waits for the command to be completed. The application might have other work to do (such as maintaining a user interface), in which case it won’t be a good decision to block while waiting for a response.
  • Since the execution of the client application is suspended while it waits for the result, it is hard for the application to decide that it would like to try to cancel the ongoing command.
  • TPSQLQuery in default mode always collects a command's entire result, buffering it in a single place. While this behavior simplifies some internal logic, it can be impractical for results containing many rows.

To avoid such limitations developers now can use the brand new Fetch-On-Demand mode, which is turned on by dsoFetchOnDemand option in the TPSQLQuery.Options set. There are limitations of course:

  • To get advantages of the Fetch-On-Demand mode one should use read-only TPSQLQuery objects. This restriction will be removed with time probably.
  • Each read-only TPSQLQuery component must have its separate TPSQLDatabase component since Fetch-On-Demand command flow will block a connection until getting the last row of the result set.

Support for built-in range and geometric field types

Previously these specific types were mapped to TStringField class. Now PostgresDAC provides new TField descendants for this:

  • TPSQLRangeField
  • TPSQLPointField
  • TPSQLCircleField
  • TPSQLBoxField
  • TPSQLLSegField

All of them will be created automatically if needed, or may be added manually in design time.

TPSQLRangeField encapsulates all built-in PostgreSQL range types: int4range, int8range, numrange, tsrange, tstzrange and daterange. Information about range value is stored in the TPSQLRange record by storing values for each bound using TPSQLRangeBound record. Depending on the underlying table field type developer may access bound values using appropriate methods AsInteger, AsFloat, etc.

Enhanced Manual

We've finished the new help system. It's rewritten it from scratch. Support for such formats provided:

  • chm,
  • pdf.
  • epub (in progress).

Full changelog:

  • [!] Fetch-On-Demand mode introduced for readonly TPSQLQuery objects
  • [!] Support for geometric types added
  • [!] TPSQLRangeField added
  • [!] Support for pre-8.0 PostgreSQL servers is discontinued
  • [!] v9.4.0 client libraries added
  • [!] v9.4.0 dump & restore libraries (pg_dump.dll, pg_restore.dll) added
  • [*] Components TPSQLUser and TBDE2PSQLDAC marked as deprecated and will be removed shortly
  • [*] EPSQLDatabaseError is raised if TPSQLDatabase is used in non-exclusive mode for TPSQLQuery with dsoFetchOnDemand
  • [*] TPSQLDatabase.CancelBackend checks for connection now to prevent AV
  • [-] "AV may occur if SQL parameter name consists from incorrect characters chain" bug fixed
  • [-] "EPSQLDatabaseError detail error properties are empty after error in TPSQLDirectQuery.Open" bug fixed

03.03.2015 - Fujitsu Develops Column-Oriented Data-Processing Engine that accelerates analytic processing more than fifty-fold on a single server with PostgreSQL open-source database



View PostgreSQL-Press related news.

Fujitsu Laboratories Ltd. today announced that it has developed a column-oriented data-storage and processing engine that enables fast analysis of large volumes of data in a database system.

In recent years, column-oriented databases have emerged as a system that allows for better speed when reading and analyzing large volumes of data, as a counterpart to existing row-oriented databases, which are suited to handling data updates. But problems have been either that the changes to row-oriented data cannot be automatically reflected in column-oriented data, or that the size of the column-oriented data is constrained by installed memory.

Fujitsu has developed an engine that, running on a PostgreSQL open-source database, without being dependent on memory capacity, instantly updates column-oriented data in response to changes in row-oriented data, and processes column-oriented data quickly. The engine quickly analyzes indexes(1), which are provided by most database systems, and can be used by developers without special consideration to whether the storage method is row-oriented or column-oriented. With a parallel-processing engine especially suited for processing column-oriented data, analyses run on a single CPU core are conducted 4 times faster than before, and one server equipped with 15 CPU cores can run analyses at least 50 times faster.

03.02.2015 - PoWA 2: Finding the Missing Index !



View PostgreSQL-Press related news.

Paris, March 2 2015

DALIBO is proud to present the second release of PoWA, the PostgreSQL Workload Analyzer.

Complete rewrite of the User Interface

The first major change is the new graphic design : we've rebuilt the web interface from scratch and placed it on a separate module called powa-web. It is now easier to move the PoWA interface out of the database server.

The new interface is based on the previous version and it adds many improvements, including:

  • More graphs
  • New types of graph : Bar / Pie Charts
  • New configuration view
  • New index suggestion widget
  • New physical resource consumption graphs
  • Better Global Query Chart
  • Breadcrumbs
  • Python 2.6, 2.7 and 3.4 compatibility
  • Better browser compatibility

 

Screenshot:

http://powa.readthedocs.org/en/latest/stats_extensions/pg_stat_statements.html#where-is-it-used-in-powa-web

Advanced Filesystem Stats

Second, the core-engine of PoWA is now a separate module too: it's called powa-archivist and we've extended it to archive any kind of internal stats. The main source of stats remains the pg_stat_statements extension but we've integrated 2 other extensions: pg_qualstats and pg_stat_kcache.

With pg_stat_kcache, PoWA is now able to gather statistics about the physical disk access and the CPU consumption of each PostgreSQL backend. This allows the DBA to get a glimpse of the OS-level cache hit ratio.

Screenshot:

http://powa.readthedocs.org/en/latest/stats_extensions/pg_stat_kcache.html#where-is-it-used-in-powa-web

Missing Index Finder + Advanced WHERE Clause Analyzer

Third major improvement, with pg_qualstats PoWA is now collecting metrics about the operations in the WHERE clause of each query. With this data, you can know what are the most common values in your SQL statements and evaluate their "selectivity". And for columns with a very high selectivity and no index, PoWA will suggest index creation to speed up you queries.

Screenshot:

http://powa.readthedocs.org/en/latest/stats_extensions/pg_qualstats.html#where-is-it-used-in-powa-web

Disruptive changes

It was a hard choice but if we want to implement ground-breaking features like the Missing Index Finder, we need to use the latest capacities of PostgreSQL and thus we decided to drop the compatibility with PostgreSQL 9.3.

Of course, we will continue to maintain PoWA v1.2 and you can continue to use it on your PostgreSQL 9.3 servers. In a nutshell, If you already use PoWA here's what you need to know:

  • If you're running PostgreSQL 9.4, we recommend that you switch to PoWA 2.0
  • If you're running PostgreSQL 9.3, you can either keep PoWA 1.2 or upgrade your PostgreSQL instance and switch to PoWA 2.0

 

Here's a detailed explanation on why we are Moving Fast and Breaking Things

02.05.2015 - PostgreSQL 9.4.1, 9.3.6, 9.2.10, 9.1.15 & 9.0.19 Released



View PostgreSQL-Press related news.

The PostgreSQL Global Development Group has released an important update with fixes for multiple security issues to all supported versions of the PostgreSQL database system, which includes minor versions 9.4.1, 9.3.6, 9.2.10, 9.1.15, and 9.0.19. This update includes both security fixes and fixes for issues discovered since the last release. In particular for the 9.4 update, there is a change to the way unicode strings are escaped for the JSON and JSONB data types.

All users should update their PostgreSQL installation at the next opportunity.

Security Fixes

This update fixes multiple security issues reported in PostgreSQL over the past few months. All of these issues require prior authentication, and some require additional conditions, and as such are not considered generally urgent. However, users should examine the list of security holes patched below in case they are particularly vulnerable.

  • CVE-2015-0241 Buffer overruns in "to_char" functions.
  • CVE-2015-0242 Buffer overrun in replacement printf family of functions.
  • CVE-2015-0243 Memory errors in functions in the pgcrypto extension.
  • CVE-2015-0244 An error in extended protocol message reading.
  • CVE-2014-8161 Constraint violation errors can cause display of values in columns which the user would not normally have rights to see.

This update also fixes the previously reported problem that, during regression testing on Windows, the test postmaster process was vulnerable to unauthorized connections. This vulnerability was fixed on non-Windows platforms in the prior update releases.

More information about these issues, as well as older patched issues, is available on the PostgreSQL Security Page.

JSON and JSONB Unicode Escapes

The handling of Unicode escape strings for JSON and JSONB in PostgreSQL 9.4.0 has been changed in a way which may break compatibility for some users. To fix some inconsistencies, type JSONB no longer accepts the escape sequence "\u0000". Type JSON accepts "\u0000" only in contexts where it does not need to be converted to de-escaped form. See the release notes for more detail.

Other Fixes and Improvements

In addition to the above, more than 60 reported issues have been fixed in this cumulative update release. Some of them affect only version 9.4, but many of them fix problems present in older versions. These fixes include:

  • Cope with the non-ASCII Norwegian Windows locale name.
  • Avoid data corruption when databases are moved to new tablespaces and back again.
  • Ensure that UNLOGGED tables are correctly copied during ALTER DATABASE operations.
  • Avoid deadlocks when locking recently modified rows.
  • Fix two SELECT FOR UPDATE query issues.
  • Prevent false negative for shortest-first regular expression matches.
  • Fix false positives and negatives in tsquery contains operator.
  • Fix namespace handling in xpath().
  • Prevent row-producing functions from creating empty column names.
  • Make autovacuum use per-table cost_limit and cost_delay settings.
  • When autovacuum=off, limit autovacuum work to wraparound prevention only.
  • Multiple fixes for logical decoding in 9.4.
  • Fix transient errors on hot standby queries due to page replacement.
  • Prevent duplicate WAL file archiving at end of recovery or standby promotion.
  • Prevent deadlock in parallel restore of schema-only dump.

In addition to the fixes above, the following contrib modules and extensions have had bugs fixed in this release: pg_upgrade, auto_explain, hstore, pageinspect, pgcrypto, pg_test_fsync, tablefunc, and xml2. Also, multiple functions across several contrib modules have been modified with the correct level of volatility. There are also multiple cleanup fixes based on minor issues found by the Coverity Scan static analyzer.

This update also contains many changes to PostgreSQL's timezone files. This includes an update to tzdata release 2015a, with updates to Chile, Mexico, Caicos Islands, and Fiji. PostgreSQL now takes date into account when assigning an offset based on a timezone abbreviation for historically changeable timezones. We have also done a general cleanup on timezone abbreviations, and added "CST" as an abbreviation for China Standard Time.

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 multiple update releases may need to perform additional post-update steps; see the Release Notes for details.

01.26.2015 - Barman 1.4.0 released



View PostgreSQL-Press related news.

26 January 2015: 2ndQuadrant is proud to announce the release of version 1.4.0 of Barman, Backup and Recovery Manager for PostgreSQL.

This major release features file-level incremental backup, a kind of full periodic backup which saves only data changes from the latest full backup available in the catalogue for a specific PostgreSQL server. Depending on the context and the database workload, the data deduplication ratio might easily reach 50-70% per full backup, leading to significant reductions in both backup time and disk space.

PostgreSQL 9.4 users will transparently benefit from the integration of Barman with "pg_stat_archiver" view. In particular, any continuous archiving problem will be immediately spotted by the "barman check" command directly on the source.

Management of WAL files has been improved, by optimising the calculation of WAL statistics, tying archiving with backup and by distinctively managing WAL trashing for exclusive and concurrent backups.

Relevant efforts in unit testing have made the code more robust. Minor bugs have also been fixed.

Many thanks for funding towards the development of this release go to BIJ12 (www.bij12.nl), Jobrapido (www.jobrapido.com), Navionics (www.navionics.com), Sovon Vogelonderzoek Nederland (www.sovon.nl), and Subito.it (www.subito.it).

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

Incremental backup

Incremental backup is a kind of full periodic backup which saves only data changes from the latest full backup available in the catalogue for a specific PostgreSQL server. The main goals of incremental backup in Barman are:

  • Reduce the time taken for the full backup process
  • Reduce the disk space occupied by several periodic backups (data deduplication)

This feature heavily relies on "rysnc" and hard links, which must be therefore supported by both the underlying operating system and the file system where the backup data resides.

The main concept is that two periodic base backups will share those files that have not changed, leading to relevant savings in disk usage. This is particularly true of VLDB contexts and, more in general, of those databases containing a high percentage of read-only historical tables. Barman implements incremental backup through a global/server option, called "reuse_backup", that transparently manages the "barman backup" command. Behaviour can also be changed at runtime through the "--reuse-backup" runtime option for the "barman backup" command.

Links

Release notes

  • Incremental base backup implementation through the "reuse_backup" global/server option. Possible values are "off" (disabled, default), "copy" (preventing unmodified files from being transferred) and "link" (allowing for deduplication through hard links).
  • Store and show deduplication effects when using "reuse_backup=link".
  • Added transparent support of pg_stat_archiver (PostgreSQL 9.4) in "check", "show-server" and "status" commands.
  • Improved administration by invoking WAL maintenance at the end of a successful backup.
  • Changed the way unused WAL files are trashed, by differentiating between concurrent and exclusive backup cases.
  • Improved performance of WAL statistics calculation.
  • Treat a missing pg_ident.conf as a WARNING rather than an error.
  • Refactored output layer by removing remaining "yield" calls.
  • Check that rsync is in the system path.
  • Include history files in WAL management.
  • Improved robustness through more unit tests.
  • Fixed bug #55: Ignore fsync EINVAL errors on directories.
  • Fixed bug #58: retention policies delete.

Realtime traffic analysis and dynamic graphs

PoWA is a workload analyzer that gives a clear view of the current activity of your PostgreSQL servers with a query runtime graph and a block hit/read graph along with a chart of time consuming requests over the specified time period.

If you zoom anywhere in one of the graphs, the chart will adjust and show you which queries were running at that time. If you click on a specific query, you will get additional graphs such as read/write time, number of rows affected, local and shared hit, etc.

A bunch of PL functions are also available to access and manage the stats.

New features and changed in UI

  • UI is now compatible with mojolicious 5.0 and more
  • UI can now connect to multiple servers, and credentials can be specified for each server
  • The timestamps are now displayed in ISO 8601 format
  • POWA_CONFIG_FILE variable has been added to allow a specific config file location and/or name
  • Better charts display on smaller screens

Credits

DALIBO would like to thank the users and developpers who contributed to this release, especially Ahmed Bessifi and Luis Pinto Da Costa.

PoWA is an open project available under the PostgreSQL License. Any contribution to build a better tool is welcome. You just have to send your ideas, features requests or patches using the GitHub tools or to powa-users@googlegroups.com (https://groups.google.com/forum/?hl=fr#!forum/powa-users)
