The comments here stated that this was just in case we ever had an ALTER OPERATOR command that could remap an operator to a different function. But those comments have been here for a long time, and no such command has come about. In the absence of such a feature, forcing the pg_proc OID to be looked up again each time we reread a stored rule or similar is just a waste of cycles. Moreover, parallel query needs a way to reread the exact same node tree that was written out, not one that has been slightly stomped on. So just get rid of this for now. Per discussion with Tom Lane.
