Well, I don't really know what a type pun is but the priobj column would
do exactly the same thing by referring to tables, types, functions, etc.
by unadorned oid, which I thought would be pretty nice. Really, in normal
mode of operation there is never a question "Does this privilege apply to
a user or a group?" it's always "Given this object and this user/group id,
do I have access?" I don't see that as a practical problem, but I'll think
about it.
