v9.0 [Feb 9, 2011]
Notable bug fixes in this update include:
1.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;
2. Work-‐around for gcc 4.6.0 bug that breaks WAL replay;
3. Fixed memory leak at end of a GiST index scan;
4.Improved handling of SSL errors;
5.Fixed SSPI login when multiple roundtrips are required (typical error reported was "The function requested is not supported");
6.Fixed VACUUM so that it always updates pg_class.reltuples and pg_class.relpages
7.Allowed the planner to assume that empty parent tables really are empty;
8.Disallowed SELECT FOR UPDATE/SHARE on sequences;
9. Fixed failure when DROP OWNED BY attempts to remove default privileges on sequences.
An app to manage, monitor and tune large numbers of Postgres database servers.
