openGauss=# \q

【预期输出】:
WITH q1 AS (SELECT * from t1 order by 1 FOR UPDATE) SELECT * FROM q1,t2 order by 1 FOR UPDATE;
ERROR: SELECT FOR UPDATE/SHARE cannot be applied to a WITH query

【实际输出】:
openGauss=# WITH q1 AS (SELECT * FROM t1 ORDER BY 1 FOR UPDATE) SELECT * FROM q1,t2 ORDER BY 1 FOR UPDATE;
WARNING: unrecognized node type: 942
