You misunderstand what that option is for: it's for trying to preserve
the exact OID values present in your old installation. It's not about
adding or removing OID columns.

No, and I don't think it'd be within pg_dump's charter to editorialize
on table definitions like that. Instead see ALTER TABLE SET WITHOUT OIDS.
