FWIW, I think that having the display depend on what that GUC is set to
is a seriously *bad* idea. It will mean that you don't actually know,
when looking at the output of \d, whether the table has OIDs or not.

I could get behind a proposal to suppress the line when there are not
OIDs, full stop; that is, we print either "Has OIDs: yes" or nothing.
But I think this patch just makes things even more surprising when
default_with_oids is turned on.
