If you're using VACUUM FULL, you're doing something wrong. :) Run lazy vacuum frequently enough (better yet, autovacuum, but cut all of 8.1's autovac parameters in half), and make sure your FSM is big enough (periodic vacuumdb -av | tail is an easy way to check that). Try a REINDEX. VACUUM FULL is especially hard on the indexes, and it's easy for them to seriously bloat. -- Decibel!, aka Jim Nasby [EMAIL PROTECTED] EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)
