Yeah, before the revert, that did:
- sjinf->syn_lefthand = replace_relid(sjinf->syn_lefthand, relid, subst);
That replace code seems to have always done a bms_copy()
-static Bitmapset *
-replace_relid(Relids relids, int oldId, int newId)
-{
- if (oldId < 0)
- return relids;
-
- /* Delete relid without substitution. */
- if (newId < 0)
- return bms_del_member(bms_copy(relids), oldId);
-
- /* Substitute newId for oldId. */
- if (bms_is_member(oldId, relids))
- return bms_add_member(bms_del_member(bms_copy(relids), oldId), newId);
-
- return relids;
-}
