By that you mean "user can write a SQL query that determines autovacuum
targets"? -1. That would bring us back to the bad old days where a
poorly-thought-out vacuum cron job would miss tables and lead to a
database shutdown. Not to mention SQL injection risks.
If we need to improve autovac's strategy, let's do that, but not by
deeming it the user's problem.
