Hello Andrei and Alexander,
Please look at the following query which produces an incorrect result since
d3d55ce57:
CREATE TABLE t(a int PRIMARY KEY, b int);
INSERT INTO t VALUES (1, 1), (2, 1);
SELECT * FROM t WHERE EXISTS (SELECT * FROM t t2 WHERE t2.a = t.b AND t2.b > 0);
a | b
---+---
1 | 1
(1 row)
I think that the expected result is:
a | b
---+---
1 | 1
2 | 1
(2 rows)
Best regards,
Alexander
