Yeah, I'm hoping there's an easier way. I'd have to put several thousand entries in the pg_autovacuum table only to remove them a few minutes later. What I really want is to disable the daemon.
Any idea why I can't just simply set autovacuum to off?

If you want to disable it only for some tables, you can put special
