What I actually suggested was not *changing* the line when it's to be
displayed, but suppressing it in the now-standard case where there's no
OIDs.

Personally I find the argument that backwards compatibility must be
preserved to be pretty bogus; we have no hesitation in changing the
output of \d anytime we add a new feature. So I don't think there's
a good compatibility reason why the line has to be spelled exactly
"Has OIDs: yes" --- but there is a consistency reason, which is that
everything else we print in this part of the \d output is of the form
"label: info".
