AFAICT during Update also, it doesn't contain useful. The only chance it would have contain something useful is when it goes for EvalPlanQual and then again comes to check for constraints. However these attributes get filled in heap_update much later. So now should the fix be that it returns an error for system column reference except for OID case?
