Hm. Seems like the restrictions here ought to be just about the same
as on index columns, no? That is, it should be roughly a test like
"no pseudo-types". The check you're proposing seems awfully specific,
and I doubt that the equivalent check in CREATE INDEX looks the same.
(But I didn't go look ... I might be wrong.)
