But INFO is not shown by default.
In fact, just about the only useful thing that emits INFO messages is
VACUUM VERBOSE, so there is a fair precedent for equating the INFO
level with lots of chatter about VACUUM.
I like to set log_min_messages to INFO (and run vacuum verbosely) while
a system is stabilizing, so adding autovacuum information there would
come in handy.
