Other thing, how will the vacuum queue be populated ? Or the "queue" here means nothing, all workers will always go through all tables to pick one based on their own criteria ? My concern here is that the current way of checking 1 DB per minute is not going to work with category #2 tables, they really have to be vacuumed continuously sometimes.
Without getting into all the details, the autovacuum naptime is a GUC variable right now, so it can be much more frequent than the current default which is 60 seconds.
