Given your test case, these queries should fail if the related
require_where GUCs are set (obviously last one should failed with either
of the GUC set):

WITH d AS (DELETE FROM test_require_where) SELECT 1;

WITH u AS (UPDATE test_require_where SET t = t) SELECT 1;

WITH d AS (DELETE FROM test_require_where), u AS (UPDATE
test_require_where SET t = t) SELECT 1;
