PostgreSQL 2011-09-26 Cumulative Bug-fix Release

The PostgreSQL Global Development Group today released minor version
updates for all active branches of the PostgreSQL object-relational
database system, including versions 9.1.1, 9.0.5, 8.4.9, 8.3.16 and
8.2.22.

All users are strongly urged to update their installations at the next
scheduled downtime.

The PostgreSQL community will stop releasing updates for version 8.2
later this year. Users are encouraged to upgrade to a newer version as
soon as possible. See our release support policy:
http://wiki.postgresql.org/wiki/PostgreSQL_Release_Support_Policy

This release fixes a long list of bugs, including several potential
crash and data-corruption issues, including:
`
* Applied upstream fix in contrib/pg_crypto for blowfish
signed-character bug (CVE-2011-2483), where encryption code could give
wrong results on platforms where char is signed (which is most),
leading to encrypted passwords being weaker than they should be;
* Work-around for gcc 4.6.0 bug that breaks WAL replay;
* Fixed memory leak at end of a GiST index scan;
* Improved handling of SSL errors;
* Fixed SSPI login when multiple roundtrips are required (typical
error reported was "The function requested is not supported");
* Fixed VACUUM so that it always updates pg_class.reltuples and
pg_class.relpages;
* Allowed the planner to assume that empty parent tables really are empty;
* Disallowed SELECT FOR UPDATE/SHARE on sequences;
* Fixed failure when DROP OWNED BY attempts to remove default
privileges on sequences.

The releases included 11 patches to 9.1, 147 patches to 9.0, 96
patches to 8.4, 73 patches to 8.3 and 52 patches to 8.2.

See the release notes for each version for a full list of changes with details.

As with other minor releases, users are not required to dump and
reload their database in order to apply this update release; you may
simply shut down PostgreSQL and update its binaries. Users skipping
more than one update may need to check the release notes for extra,
post-update steps.
