The problem appears to be that ALTER TABLE SET WITHOUT OIDS doesn't make
the index on the OID column go away.
I don't have a strong opinion on whether to fix this by forcing a drop
of the index or by rejecting the ALTER command. Seems like we have to
do one or the other though.
This is actually just the simplest case of a dependency on the OID
column... whatever the fix is, it has to handle the general case.
