Removing all track* GUCs would only make sense if we are going to make
autovacuum mandatory, i think. And i thought update_process_title was
introduced due to performance complaints on some platforms which can't easily
be resolved?
Yes, update_process_title on FreeBSD defaults to 'off' as the overhead
based on how FreeBSD does the update was enough to make a noticeable
difference in performance ... suspect that is the same for all the *BSDs,
not sure about any other platform though ... maybe Windows?
