Of course. But we have already done the update-once-every-half-second
bit --- that was how pg_stat_activity used to work --- and our users
made clear that it's not good enough. So I don't see us expending
significant effort to convert the setproctitle code path to that
approach. The clear way of the future for expensive-setproctitle
platforms is just to turn it off entirely and rely on the new
pg_stat_activity implementation.
