Please look at a new anomaly introduced with 53af9491a. When running the
following script:
CREATE TABLE t (a int, b int, PRIMARY KEY (a, b));
CREATE TABLE pt (a int, b int, FOREIGN KEY (a, b) REFERENCES t(a, b))
PARTITION BY LIST (a);
CREATE TABLE tp1 (x int, a int, b int);
ALTER TABLE tp1 DROP COLUMN x;
ALTER TABLE pt ATTACH PARTITION tp1 FOR VALUES IN (1);
ALTER TABLE pt DETACH PARTITION tp1;
I've also discovered another anomaly with a similar setup, but it's not
related to 53af9491a.
CREATE TABLE t (a int, PRIMARY KEY (a));
INSERT INTO t VALUES (1);
CREATE TABLE pt (b int, a int) PARTITION BY RANGE (a);
ALTER TABLE pt DROP COLUMN b;
ALTER TABLE pt ADD FOREIGN KEY (a) REFERENCES t ON DELETE SET DEFAULT (a);
CREATE TABLE tp1 PARTITION OF pt FOR VALUES FROM (1) TO (2);
ALTER TABLE pt DETACH PARTITION tp1;
DELETE FROM t;
\d+ t
This script ends up with:
ERROR: invalid attribute number 2
ERROR: cache lookup failed for attribute 2 of relation 16398
(Perhaps it deserves a separate discussion.)
Best regards,
Alexander
