Right, the server log should tend to being empty if there is nothing
unusual happening. I recall that someone once complained about every
checkpoint run making an entry; and every autovacuum run making one
would be about the same. Certainly, there is room for more fine-tuning
here, but the all-important question "Has autovacuum ever run
(recently)" can now be easily answered in 8.2, so we're good.
