Datanamic has released a new version of Datanamic DataDiff for PostgreSQL. Datanamic DataDiff allows the user to compare the data in two databases, view the differences, automatically generate safe data change scripts or apply the changes to the destination database directly.
Version 4 is almost completely re-designed with a new modern user interface, an improved comparison engine and new comparison options. Three (3) editions support PostgreSQL: the MultiDB edition, the PostgreSQL edition and the CrossDB edition. The CrossDB edition allows you to synchronize data between different database platforms (including PostgreSQL).
More information can be found on the Datanamic DataDiff for PostgreSQL product pages.

DALIBO is proud to announce the release of pgBadger v3, the new PostgreSQL log analyzer. pgBadger is built for speed with fully detailed reports from your PostgreSQL log file.
This new release brings significant improvements. All pgBadger users should upgrade as soon as possible.pgBadger 3 parallel log parsing
The first versions of pgBadger were bound to only one CPU. The PostgreSQL log files were scanned sequentially. Analyzing very large log files could take several hours.
This limitation is now removed. You can use as many CPU cores as you want and scan your logs in parallel.
To enable parallel processing, you just have to use the -j N option, N being the number of cores you want to use.
Please note that the parallel mode has a little drawback. With this method, some queries may be truncated. If you enable N cores, then result may differ in a maximum of N queries per log file.
However, this is a minor issue: parallel mode is interesting if you have millions of queries to analyze. And if you have millions of queries in a log file, you can afford to loose a few as it's quite unlikely that the lost queries would have changed the overall results.
However, to avoid this problem, you can use the pgBadger "per-file parallel mode" to analyze your logs but with lower performance than the standard parallel mode. To enable this behaviour, you have to use the "-J N" option instead of "-j N". In per-file mode, the performances start being really interesting when there's hundreds of small log files (e.g. 10MB rotation size limit) and with at least 8 cores.How fast is pgBadger 3?
The goal was to allow pgBadger to use as many cores as specified to have parallel log parsing. Here are some performance results using pgbadger on five log files for a total of 9.5 GB:
We feel this performance gain is quite interesting :)New binary format
In addition to the classic HTML, TXT and Tsung output formats, pgBadger 3 is now able to generate a binary input/output format. This new format is useful if you only want to store the log statistics and generate the HTML report with graph later.
In a nutshell, the two main activities of pgBadger are parsing and reporting. With this binary format, you can now split those activities and run them at different times. For exemple, you can parse your log once a day, and generate the HTML reports only when needed.
You can also combine several binary files to . For Instance, you may create a binary report every week and aggregate the last 4 week reports to build a monthly report in HTML.
This new binary format is also compatible with other tools such as pgShark https://github.com/dalibo/pgshark/.More stats, more pie charts!
This major release also has additional features:
... and many bugfixes .
For the complete list of changes, please checkout the release note on https://github.com/dalibo/pgbadger/blob/master/ChangeLogDeprecated options
WARNING : for the sake of simplicity, the ''--enable-log_min_duration'' and ''--enable-log_duration'' command line options have been removed. pgbadger is now parsing any log_duration, log_statement and log_min_duration_statement lines without distinction and adapt the reports following those lines.
If you are running pgBadger using cron, please take care: if one of theses options appears in the command line, pgbadger will refuse to start.Links & Credits

2ndQuadrant is proud to announce the release of version 1.2.0 of Barman, Backup and Recovery Manager for PostgreSQL.
This major release introduces automated support for retention policies based on redundancy of periodical backups or recovery window.
Retention policies are integrated by a safety mechanism that allows administrators to specify a minimum number of periodical backups that must exist at any time for a server.
For a complete list of changes, see the "Release Notes" section below.Backup retention policies
A backup retention policy is an user-defined policy that determines how long backups and related archive logs (Write Ahead Log segments in PostgreSQL) need to be retained for recovery procedures.
Through the 'retention_policy' configuration option, Barman retains the periodical backups required to satisfy the current retention policy, and any archived WAL files required for the complete recovery of those backups.
Barman users can define a retention policy in terms of backup redundancy (how many periodical backups, e.g. 5) or a recovery window (how long, e.g. 3 months).
Minimum redundancy safety --
Through the 'minimum_redundancy' configuration option, Barman controls the minimum number of backups available at any time in the catalogue for a specific server. This feature will protect users from accidental delete operations.
The open-source development of retention policies under GPL has been sponsored by a large European company that opted to remain anonymous.

About Barman --
Barman (Backup and Recovery Manager) is an open-source administration tool for disaster recovery of PostgreSQL servers written in Python. It allows your organisation to perform remote backups of multiple servers in business critical environments and help DBAs during the recovery phase. Barman most wanted features include backup catalogues, retention policies, remote recovery, archiving and compression of WAL files and backups.
Built on top of PostgreSQL's robust and reliable Point-In-Time-Recovery technology, Barman allows database administrators to manage the backup and recovery phases of several PostgreSQL database servers from a centralised location, using an intuitive command interface. Barman is distributed under GNU GPL 3.
The PostgreSQL Global Development Group has released a security update to all current versions of the PostgreSQL database system, including versions 9.2.3, 9.1.8, 9.0.12, 8.4.16, and 8.3.23. This update fixes a denial-of-service (DOS) vulnerability. All users should update their PostgreSQL installations as soon as possible.
The security issue fixed in this release, CVE-2013-0255, allows a previously authenticated user to crash the server by calling an internal function with invalid arguments. This issue was discovered by independent security researcher Sumit Soni this week and reported via Secunia SVCRP, and we are grateful for their efforts in making PostgreSQL more secure.
Today's update also fixes a performance regression which caused a decrease in throughput when using dynamic queries in stored procedures in version 9.2. Applications which use PL/pgSQL's EXECUTE are strongly affected by this regression and should be updated. Additionally, we have fixed intermittent crashes caused by CREATE/DROP INDEX CONCURRENTLY, and multiple minor issues with replication.
This release is expected to be the final update for version 8.3, which is now End-of-Life (EOL). Users of version 8.3 should plan to upgrade to a later version of PostgreSQL immediately. For more information, see our Versioning Policy.
This update release also contains fixes for many minor issues discovered and patched by the PostgreSQL community in the last two months, including:
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.
