Yes, I think that makes sense.

It doesn't really bother me ;). I just didn't understand why it existed.
I do think that it is conceivable that we want to be able to suppress
the examination of some settings, but I would think that would apply to
SHOW just the same as SHOW ALL. It seems that anything I can SHOW should
be there when I do SHOW ALL. Maybe it should be GUC_NO_SHOW and apply to
both?
