FSM as I understand it gets it information from vacuum, and has an space marker removed when an insert uses the tuple. Determining when vacuum runs would be based more on Deletes / updates than anything wouldn't it? Anyhow, I'd be curious to know your full thoughts on autovacuum and how it may work. -- Rod Taylor <[EMAIL PROTECTED]> PGP Key: http://www.rbt.ca/rbtpub.asc
