Specifying a locking clause (FOR UPDATE/SHARE) that names a GRAPH_TABLE alias currently results in an unhelpful "unrecognized RTE type: 8" error. This commit explicitly prohibits specifying a locking clause on a GRAPH_TABLE alias, raising a more user-friendly error instead. (Locking clause support for GRAPH_TABLE could be added as a separate feature in the future.)
