Hi Alexander,

I've discovered that starting from d3d55ce57 the following query:
CREATE TABLE t(a int PRIMARY KEY);
WITH tt AS (SELECT * FROM t)
UPDATE t SET a = tt.a + 1 FROM tt
WHERE tt.a = t.a RETURNING t.a;
triggers an error "variable not found in subplan target lists".
(Commits 8a8ed916f and b5fb6736e don't fix this, unfortunately.)
Best regards,
Alexander
