I do think differently.
Autovacuum isn't perfect, and you shouldn't make it too aggressive
since it does generate a lot of I/O activity. If you can pick a time
where it will be able to run without interfering too much, running
vacuum "manually" (where manually could easily be a cron task, ie,
automatically but coming from outside the database software itself),
you'll be able to dial down autovacuum and have more predictable load
overall.
