E.89. Release 7.4.17

Release date: 2007-04-23

This release contains fixes from 7.4.16, including a security fix. For information about new features in the 7.4 major release, see Section E.106.

E.89.1. Migration to Version 7.4.17

A dump/restore is not required for those running 7.4.X. However, if you are upgrading from a version earlier than 7.4.11, see the release notes for 7.4.11.

E.89.2. Changes

  • Support explicit placement of the temporary-table schema within search_path, and disable searching it for functions and operators (Tom)

    This is needed to allow a security-definer function to set a truly secure value of search_path. Without it, an unprivileged SQL user can use temporary objects to execute code with the privileges of the security-definer function (CVE-2007-2138). See CREATE FUNCTION for more information.

  • /contrib/tsearch2 crash fixes (Teodor)

  • Fix potential-data-corruption bug in how VACUUM FULL handles UPDATE chains (Tom, Pavan Deolasee)

  • Fix PANIC during enlargement of a hash index (bug introduced in 7.4.15) (Tom)
