A while back it was pointed out the that the Windows version of 8.2.3 had a bug that prevented auto-vacuum from working correctly. http://archives.postgresql.org/pgsql-general/2007-04/msg00139.php I wasn't able to determine from the release notes if this bug was fixed in versions 8.2.4 or 8.2.5. Does any know if it was?
