PostgreSQL 9.2 beta becomes available for testing, focusing on JSON and scalability

The PostgreSQL Global Development Group have announced the first beta release for the latest iteration of their object-relational database.

Fans of Postgres can now get their hands on the latest version of the object-relational database, through the announcement of PostgreSQL 9.2’s first beta version.

The PostgreSQL Project has encouraged users to download PostgreSQL 9.2 Beta 1 to begin testing and utilise the major increases in performance and both vertical and horizontal scalability.

Three new features have been ushered into the fold this time round. The most interesting of the bunch is JSON data support, linking up the object-relational world to enable the creation of hybrid document-relational databases. New range types make it possible to support new types of calendar, time-series and analytic applications.

One new functionality is index-only scans, allowing users to avoid inefficient scans of base tables and disregard underlying unneeded ones. This will improve the efficiency of index-only scans somewhat – they happen automatically but need to be fine-tuned to be really effective.

Read-only workloads now boasts the ability to scale to 64 cores and make over 300,000 queries per second (a big step up if this is the case) whilst there’s also improvements to data write speeds. Another big change comes in the form of cascading replication support for geographically-distributed standby databases. This version also brings greater reductions in CPU power consumption despite the raft of enhancements.

For a full listing of the features in version 9.2 Beta, see the release notes. PostgreSQL depends on the community’s feedback in these early stages to eliminate the bugs, maintain high performance and add in new intricacies, so it’s well worthwhile telling them via testing and reporting issues. You can get the binaries for Windows, Mac OS X, Linux, FreeBSD and Solaris from the download page and if it goes swimmingly we should see 9.2 proper, come out in September. Get testing!
