E.20. Release 8.2.4

Release Date: 2007-04-23

This release contains a variety of fixes from 8.2.3, including a security fix. For information about new features in the 8.2 major release, see Section E.24.

E.20.1. Migration to Version 8.2.4

A dump/restore is not required for those running 8.2.X.

E.20.2. 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.

  • Fix shared_preload_libraries for Windows by forcing reload in each backend (Korry Douglas)

  • Fix to_char() so it properly upper/lower cases localized day or month names (Pavel Stehule)

  • /contrib/tsearch2 crash fixes (Teodor)

  • Require COMMIT PREPARED to be executed in the same database as the transaction was prepared in (Heikki)

  • Allow pg_dump to do binary backups larger than two gigabytes on Windows (Magnus)

  • New traditional (Taiwan) Chinese FAQ (Zhou Daojing)

  • Prevent the statistics collector from writing to disk too frequently (Tom)

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

  • Fix bug in domains that use array types (Tom)

  • Fix pg_dump so it can dump a serial column's sequence using -t when not also dumping the owning table (Tom)

  • Planner fixes, including improving outer join and bitmap scan selection logic (Tom)

  • Fix possible wrong answers or crash when a PL/pgSQL function tries to RETURN from within an EXCEPTION block (Tom)

  • Fix PANIC during enlargement of a hash index (Tom)

  • Fix POSIX-style timezone specs to follow new USA DST rules (Tom)
