Heh. Probably we should just drop that special treatment of the
catalogname field --- that was always premature optimization,
given that (I think) we don't ever store RangeVar in the catalogs.
The alternative would be to also lobotomize comparisons of RangeVars
by marking the field equal_ignore, but what's the point?
