Thank you, David!

Please look at another anomaly introduced with 590b045c3:
echo "
CREATE TABLE t(f int, t int);
INSERT INTO t VALUES (1, 1);

WITH RECURSIVE sg(f, t) AS (
SELECT * FROM t t1
UNION ALL
SELECT t2.* FROM t t2, sg WHERE t2.f = sg.t
) SEARCH DEPTH FIRST BY f, t SET seq
SELECT * FROM sg;
" | timeout 60 psql

triggers
TRAP: failed Assert("chunk->requested_size < oldsize"), File: "generation.c", Line: 842, PID: 830294

Best regards,
Alexander
