        t1.ancestor_id AS ancestor_id,
        t2.descendant_id AS descendant_id,
        SUM(t1.paths*t2.paths)::bigint AS paths,
        MIN(t1."cost"+t2."cost")+1::bigint AS "cost"
    FROM db_set_membership_closure t1, db_set_membership_closure t2
    WHERE t1.descendant_id=new_parent_id AND t2.ancestor_id=NEW_child_id
    GROUP BY t1.ancestor_id, t2.descendant_id
    UNION
    SELECT
        NEW_parent_id AS ancestor_id,
        descendant_id AS descendant_id,
