But what possible reason is there for keeping it in pg_control?
AFAICS that would just mean that we'd need special code for setting it,
instead of making use of all of Peter's hard work on GUC.

We should be moving away from special-case parameter mechanisms, not
inventing new ones without darn good reasons for them.
