I think there are two things people typically want to know from the logs:
1) Is autovacuum running
2) Did autovacuum take action (issue a VACUUM or ANALYZE)
I don't think we need mention the name of each and every database we
touch, we can, but it should be at a lower level like DEBUG1 or something.
I don't know what logging level these thing should go at, but I for one
would like them to be fairly high easy to get to, perhaps NOTICE?
