Bug reference: 18550
Logged by: Alexander Lakhin
Email address: exclusion@gmail.com
PostgreSQL version: 17beta2
Operating system: Ubuntu 22.04
Description:
The following script:
CREATE TABLE t1 (a int);
CREATE TABLE t2 () INHERITS (t1);
DROP TABLE t2;
CREATE TABLE t (a int) PARTITION BY LIST (a);
ALTER TABLE t ATTACH PARTITION t1 FOR VALUES IN (1);
INSERT INTO t1 VALUES (1);
UPDATE t1 SET a = 2 WHERE a = 1
triggers an assertion failure (due to t1 is not recognized as a leaf
partition):
TRAP: failed Assert("rel->rd_rel->relkind == RELKIND_PARTITIONED_TABLE"),
