pg_dump would probably actually prefer not having type info in the
output string; it'll just have to strip it off in most places. But
I don't have a good feeling for the needs of other applications,
so I was asking what other people thought.
If we supported both ways via two datatypes, we'd have all the bases
covered; I'm just wondering if it's worth the trouble.

PS: interesting thought about enum ...
