Well, CTAS is a vastly inferior solution because you'd have to manually
move indexes, constraints, FKs, etc to the new table. Plus it's just as
slow if not slower than the proposed rewriting code. I think that
Andrew's complaint about not putting barriers in the way of removing
OIDs would apply pretty strongly to that approach.
