It is useful to know if the database had to do recovery, though, and
if it did do recovery, it would be useful to know how long it took if
the subsequent startup took a real amount of time.
BTW, this is a real problem I've seen on a database with 500k entries
in pg_class... it takes several minutes to finish starting after the
'Postmaster is ready' message.
