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.) regards, tom lane
