PostgreSQL 9.4.4, 9.3.9, 9.2.13, 9.1.18 & 9.0.22 Released! Posted on June 12, 2015 2015-06-12 Update Release The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 9.4.4, 9.3.9, 9.2.13, 9.1.18 and 9.0.22. This release primarily fixes issues not successfully fixed in prior releases. It should be applied as soon as possible all users of major versions 9.3 and 9.4. Other users should apply at the next available downtime. Crash Recovery Fixes Earlier update releases attempted to fix an issue in PostgreSQL 9.3 and 9.4 with "multixact wraparound", but failed to account for issues doing multixact cleanup during crash recovery. This could cause servers to be unable to restart after a crash. As such, all users of 9.3 and 9.4 should apply this update as soon as possible. Servers previously upgraded to PostgreSQL 9.3 using pg_upgrade, even those servers now running PostgreSQL 9.4 due to another upgrade, may experience an immediate autovacuum of all tables after applying this update. For large databases, consider a controlled manual VACUUM, before updating, to better regulate the performance consequences of this critical maintenance. Please see the release notes for details. Other Fixes and Improvements In addition to the above, a few other minor issues were patched in this release. These fixes include: • Prevent failure to invalidate relation cache init file • Avoid deadlock between new sessions and CREATE/DROP DATABASE • Improve query planning for semi-joins and anti-joins ...
