Well, you have to turn on the stats collector, so you will pay a little
bit of a performance penalty for that. I doubt you'll notice it unless
you're really close to the edge. You do have to restart the database to
enable the stats collector if it's off. The pg_stat_activity stuff is
pretty essential for debugging problems in the database.
