Curiously enough, I was just thinking about that after reading Craig's
post. autovacuum will do this, sort of, if it's turned on --- but its
reaction time is measured in minutes typically so that may not be good

Another thing we've been beat up about in the past is that loading a
pg_dump script doesn't ANALYZE the data afterward...
