We had a proposed design to tell autovac when not to run (or rather,
when to switch settings very high so that in practice it'd never run).
At some point somebody said "but we can just change autovacuum=off in
postgresql.conf via crontab when the high load period starts, and turn
it back on afterwards" --- and that was the end of it.
