If they are not, your database starts to bloat and you need ugly hacks like vacuum full to recover the dead space. In 8.1, clog is only cleared by database-wide vacuums, which IIRC autovac doesn't do unless it does a for-Xid-wraparound run, which is not often. Probably a weekly database-wide vacuum (not full, i.e. vacuumdb without -f) is enough. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
