Release Date

This release contains a small number of fixes from 9.2.12. For information about new features in the 9.2 major release, see Section E.49, « Release 9.2 ».

E.36.1. Migration to Version 9.2.13

A dump/restore is not required for those running 9.2.X.

However, if you are upgrading from a version earlier than 9.2.11, see Section E.38, « Release 9.2.11 ».

E.36.2. Changes

  • Fix rare failure to invalidate relation cache init file (Tom Lane)

    With just the wrong timing of concurrent activity, a VACUUM FULL on a system catalog might fail to update the « init file » that's used to avoid cache-loading work for new sessions. This would result in later sessions being unable to access that catalog at all. This is a very ancient bug, but it's so hard to trigger that no reproducible case had been seen until recently.

  • Avoid deadlock between incoming sessions and CREATE/DROP DATABASE (Tom Lane)

    A new session starting in a database that is the target of a DROP DATABASE command, or is the template for a CREATE DATABASE command, could cause the command to wait for five seconds and then fail, even if the new session would have exited before that.
