Download PostgreSQL 8.4.1 / 8.3.8 / 8.2.14 / 8.1.18 / 8.0.22 / 7.4.26

PostgreSQL is an open source relational database management system that can be run on various operating systems. The developers have released another series of new versions with 8.4.1, 8.3.8, 8.2.14, 8.1.18, 8.0.22 and 7.4.26 as version numbers. This fixes several bugs and since one of them could cause a denial of service, everyone is advised to update. The announcement of these versions looks like this:

PostgreSQL 2009-09-09 Security Update

The PostgreSQL Project today released minor versions updating all active branches of the PostgreSQL object-relational database system, including versions 8.4.1, 8.3.8, 8.2.14, 8.1.18, 8.0.22, and 7.4.26. This release fixes one moderate-risk and two low-risk security issues: an authentication issue, a denial of service issue, and a privilege-escalation exploit. All users should upgrade their database installations as soon as reasonably possible.

This update release also fixes the “could not reattach shared memory” issue which has plagued many Windows PostgreSQL users, and updates time zone files for several countries. There are 23 other minor fixes, many of them affecting only version 8.4. See the release notes for full details.

As with other minor releases, users are not required to dump and reload their database in order to apply this update release; you may simply shut down PostgreSQL and update its binaries. Users skipping more than one update may need to check the release notes for extra, post-update steps.
