There is; I know that things like web session tables aren't handled very well by autovacuum if there are any moderately large tables (anything that will take more than a few minutes to vacuum). Eventually we should be able to accommodate that case with multiple workers, but we'll need a mechanism to ensure that at least one worker doesn't get tied up in large vacuums. -- Jim Nasby [EMAIL PROTECTED] EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)
