[Description]
the only updatable columns we support are those that are Vars referring to user columns of the underlying base relation.The view targetlist may contain resjunk columns (e.g., a view defined like "SELECT * FROM t ORDER BY a+b" is auto-updatable) but such columns are not auto-updatable, and in fact should never appear in the outer query's targetlist.
