Hello Noah,

Please look also at another anomaly, I've discovered.
An Assert added with d5f788b41 may be falsified with:
CREATE TABLE t(a int PRIMARY KEY);
INSERT INTO t VALUES (1);
CREATE VIEW v AS SELECT * FROM t;
MERGE INTO v USING (VALUES (1)) AS va(a) ON v.a = va.a
WHEN MATCHED THEN DO NOTHING
WHEN NOT MATCHED THEN DO NOTHING;
TRAP: failed Assert("resultRelInfo->ri_TrigDesc"), File: "nodeModifyTable.c", Line: 2891, PID: 1590670
Best regards,
Alexander
