RESTRICT, yes.  I don't know about ONLY being sensible as we don't
really deal with inheritance and foreign tables very cleanly today, as I
said up-thread, so I'm not sure if we really want to put in the effort
that it'd require to figure out how to make ONLY make sense.  The
question about how to handle IDENTITY is a good one.  I suppose we could
just pass that down and let the FDW sort it out..?
