Handle OID column inheritance correctly in ALTER TABLE ... INHERIT. Inheritance operations must treat the OID column, if any, much like regular user columns. But MergeAttributesIntoExisting() neglected to do that, leading to weird results after a table with OIDs is associated to a parent with OIDs via ALTER TABLE ... INHERIT.
