Could I suggest renaming log_autovacuum to log_autovacuum_min_duration?
I found it confusing to when setting it to 0 *enabled* logging so I imagine
others will be as well. Also it seems we may want to have other messages
logged from autovacuum so it would be better to leave room for other
log_autovacuum_* parameters and possibly a master "log_autovacuum" parameter.
