IIRC there is per operation threshold. If update threshold is 5% and table is 2% updatedit, then it should not look at it at all. It's worth mentioning that you should start auto vacuum daemon on a clean database. i.e. no pending vacuum. It is not supposed to start with a database which has lots of clean up pending. The essence of auto vacuum daemon is to maintain a clean database in clean state.. I agree, specifying per table thresholds would be good in autovacuum..
