+1. I'm not as convinced as you are that we'll replace the GUC later,
but in any case this is an accurate description of the current
semantics. And I'm really *not* in favor of fudging the name with
the intent of changing the GUC's semantics later --- that would fail
all sorts of compatibility expectations.
