OK, that part is done.

Interesting idea. I had forgotten that for server messages, LOG is at
the top, and ERROR, NOTICE, etc are below it. We could make them
NOTICE, but then all user NOTICE messages appear in the logs too. Yuck.
Do we want to LOG everytime autovacuum does something? Is that going to
fill up the logs worse than the per-database line?
The real issue is that we give users zero control over what autovacuum
logs, leading to the TODO item. I guess the question is until the TODO
item is done, what do we want to do?
How do people like the idea of having this in postgresql.conf:
autovacuum_set = 'set log_min_messages = ''error'''
and set autovacuum to output notice/info/error messages as desired by
the administrator? This shouldn't be too hard to do, and it is very
flexible.
