Apologies if this is already reported, but there’s a crasher in recursive queries at the head of the current development that happened to be exercised by our regression suite. Here is a core-only reproduction.
CREATE TABLE foo (id integer, x integer, y integer);
INSERT INTO foo VALUES (1, 0, 1);
INSERT INTO foo VALUES (2, 1, 2);
INSERT INTO foo VALUES (3, 2, 3);
WITH RECURSIVE path (id, x, y) AS (
SELECT id, x, y FROM foo WHERE id = 1
UNION
SELECT foo.id, foo.x, foo.y
FROM path, foo
WHERE path.y = foo.x
)
SELECT 'crash', id, x, y FROM path;
Thanks!
ATB,
P
