Security and maintenance release for PostgreSQL: versions 9.1.3, 9.0.7, 8.4.11 and 8.3.18

Today, PostgreSQL Global Development Group released new versions of all active branches. This includes three security bugfixes, two of which are pretty obscure and one that fixes a possible security issue with restoring un-sanitized output from pg_dump. Details about the security issues are included in the release announcement.

Some other bug and performance fixes in this minor release include:

  • Fix btree index corruption from insertions concurrent with vacuuming
  • Avoid crashing when we have problems deleting table files post-commit
  • Fix recently-introduced memory leak in processing of inet/cidr
  • Fix postmaster to attempt restart after a hot-standby crash

Upgrade as soon as you can!
