The AXLE Consortium are pleased to announce the start of the AXLE database research project, funded by European Union under FP7 grant. axleproject.eu

The objectives of the AXLE project are to greatly improve the speed and quality of decision making on real-world data sets. AXLE aims to make these improvements generally available through high quality open source implementations via the PostgreSQL database and Orange data visualisation and data mining tools.

AXLE project members are

• Barcelona Supercomputing Centre (BSC)
• Portavita
• University of Manchester
• University of Ljubljana
• Coordinated by 2ndQuadrant

Areas of research will include data analysis algorithms for Big Data, advanced hardware architectures, data visualisation and security. Target environments are real-world data in the 10-100 TB range.

"Real world data needs good security too, so we'll be making sure we have high grade security that works well even with high performance requirements", says Simon Riggs, CTO of 2ndQuadrant and Principal Investigator for the AXLE project. "We're very happy that the European Union has recognised the potential of the PostgreSQL database to provide effective database analytics for a broad range of business, research and public services."

First deliverables from the project will be submitted to PostgreSQL version 9.4, available in 2014 and will continue in later releases.

Project updates will be available regularly here as work continues.

Sprout is a project dedicated to a nested key-value pair programming language native to the Entity Attribute Value database model. Its environment is a Relational Database Management System, specifically Postgres 9. It is implemented with Procedural SQL and employs a key-value translator vernacular to EAV data model. The model provides storage of objects, object metadata definitions and program code. Sprout executes requests via SQL client interface and returns objects of various types. It has characteristics of a column-oriented database.

Dalibo is proud to announce the release of Ora2Pg 11.1. This major release adds support to multiprocessing so that you can now export data in parallel mode. Importing data from an Oracle database is now ten times faster. With this new feature, Ora2Pg performances are closer to the ones you'd get with any ETL.

Since 2001, Ora2Pg is the best solution to migrate data from Oracle to PostgreSQL and is used by thousands of companies around the world to switch from the most expensive proprietary RDBMS to the most advanced Open Source RDBMS!

Ora2pg 11.1 also brings important improvements :

• You can now generate XML transformation files for Kettle (see http://kettle.pentaho.com/).
• Faster scan of Oracle databases containing huge number of objects.
• Faster partition data export with direct import to tables partition.
• Bug fixes on RAW or LONG RAW data export.
• PL/SQL to PL/PGSQL code rewrite.

Gilles Darold, the project leader and main developer of Ora2Pg, explains: "The development of ora2pg is really fast because more and more companies are moving from Oracle to PostgreSQL. This new version brings speed improvements to migrate multi-terabyte databases faster. For most users, lowering the migration time is critical because it means less downtime during the switch from Oracle to PostgreSQL."

These performance enhancements were developed by Dalibo in collaboration with Photobox, Europe's largest online photo processing service and Bouygues Telecom, a major mobile network operator and ISP in France.

Dalibo would like to thank the developers who submitted patches and the users who reported bugs and feature requests, especially : Dominique Fourdrinoy, Ludovic Penet, Thomas Ogrisegg, Alex Delianis, Pierre-Marie Petit and mrojasaquino. Ora2Pg is an open project. Any contribution to build a better tool is welcomed. You just have to send your ideas, features requests, or patches using the GitHub tools at https://github.com/darold/ora2pg.

About Ora2Pg :

Ora2Pg is an easy and reliable tool to migrate data from Oracle to PostgreSQL. It is developed since 2001 by Gilles Darold, also author of pgBadger, a PostgreSQL performance tool. Ora2Pg can export most of the Oracle objects (table, view, tablespace, sequence, indexes, trigger, grant, function, procedure, package, partition, data, blob and external table).

Ora2Pg works on any platform and is available under the GPL v3 licence.

The PostgreSQL project has again been selected to take part in Summer of Code for 2013. Google will be funding several students to work with mentors from our project in order to hack PostgreSQL code for the summer.

Applications for students open April 22nd. Our Summer Of Code page has all the information you need about applying this year.

If you are connected with a university, please make sure that students know about this opportunity. If you are a student, please apply!

The PostgreSQL Global Development Group has released a security update to all current versions of the PostgreSQL database system, including versions 9.2.4, 9.1.9, 9.0.13, and 8.4.17. This update fixes a high-exposure security vulnerability in versions 9.0 and later. All users of the affected versions are strongly urged to apply the update immediately.

A major security issue fixed in this release, CVE-2013-1899, makes it possible for a connection request containing a database name that begins with "-" to be crafted that can damage or destroy files within a server's data directory. Anyone with access to the port the PostgreSQL server listens on can initiate this request. This issue was discovered by Mitsumasa Kondo and Kyotaro Horiguchi of NTT Open Source Software Center.

Two lesser security fixes are also included in this release: CVE-2013-1900, wherein random numbers generated by contrib/pgcrypto functions may be easy for another database user to guess, and CVE-2013-1901, which mistakenly allows an unprivileged user to run commands that could interfere with in-progress backups. Finally, this release fixes two security issues with the graphical installers for Linux and Mac OS X: insecure passing of superuser passwords to a script, CVE-2013-1903 and the use of predictable filenames in /tmp CVE-2013-1902. Marko Kreen, Noah Misch and Stefan Kaltenbrunner reported these issues, respectively.

We are grateful for each developer's efforts in making PostgreSQL more secure.

This release also corrects several errors in management of GiST indexes. After installing this update, it is advisable to REINDEX any GiST indexes that meet one or more of the conditions described below.

This update release also contains fixes for many minor issues discovered and patched by the PostgreSQL community in the last two months, including:

• Fix GiST indexes to not use "fuzzy" geometric comparisons for box, polygon, circle, and point columns
• Fix bugs in contrib/btree_gist for GiST indexes on text, bytea, bit, and numeric columns
• Fix bugs in page splitting code for multi-column GiST indexes
• Fix buffer leak in WAL replay causing "incorrect local pin count" errors
• Ensure crash recovery before entering archive recovery during unclean shutdown when recovery.conf is present
• Avoid deleting not-yet-archived WAL files during crash recovery
• Fix race condition in DELETE RETURNING
• Fix possible planner crash after adding columns to a view depending on another view
• Eliminate memory leaks in PL/Perl's spi_prepare() function
• Fix pg_dumpall to handle database names containing "=" correctly
• Avoid crash in pg_dump when an incorrect connection string is given
• Ignore invalid indexes in pg_dump and pg_upgrade
• Include only the current server version's subdirectory when backing up a tablespace with pg_basebackup
• Add a server version check in pg_basebackup and pg_receivexlog
• Fix contrib/dblink to handle inconsistent settings of DateStyle or IntervalStyle safely
• Fix contrib/pg_trgm's similarity() function to return zero for trigram-less strings
• Enable building PostgreSQL with Microsoft Visual Studio 2012
• Update time zone data files for DST law changes in Chile, Haiti, Morocco, Paraguay, and some Russian areas

As always, update releases only require installation of packages and a database system restart. You do not need to dump/restore or use pg_upgrade for this update release. Users who have skipped multiple update releases may need to perform additional, post-update steps; see the Release Notes for details.

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:

• with 1 core => 1h 41m 18s
• with 2 cores => 50m 25s
• with 4 cores => 25m 39s
• with 8 cores => 15m 58s

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:

• New pie graph to show number of autovacuum per table and number of tuples removed by autovacuum per table
• No more distinction between log_duration, log_statement and log_min_duration_statement format
• New report of tuples/pages removed in report of VACUUM by table
• New VACUUM and ANALYZE hourly reports and graphs

... and many bugfixes .

For the complete list of changes, please checkout the release note on https://github.com/dalibo/pgbadger/blob/master/ChangeLog

Deprecated 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.
