Well, I have an equally lame reason for wanting to not run autovac:
it'll interfere with profiling because the autovac daemon will drop a
gmon.out file once a minute or so, and maybe overwrite a profiling run's
results before you can print them out.
But AFAICS both of these wishes can be served pretty well just by
increasing autovacuum_naptime to some large value, once a day maybe.
They don't strike me as compelling reasons why autovac should be turned
off entirely.
