I'm skeptical about this. I don't think we want to wind up with a reg*
type for every system catalog, so there needs to be some rule about which
ones it's worth the trouble for. The original idea was to provide a reg*
type if the lookup rule would be anything more complicated than "select
oid from <catalog> where name = 'foo'". We went beyond that with
regnamespace and regrole, but I think there was a sufficient argument of
usefulness for those two. I don't see that reglanguage has enough of
a use-case.
