Subject: BUG #18674: Partitioned table doesn't depend on access method it uses
Date: Sat, 26 Oct 2024 06:00:00 +0000
Message-ID: <18674-1ef01eceec278fab@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 18674
Logged by: Alexander Lakhin
Email address: exclusion@gmail.com
PostgreSQL version: 17.0
Operating system: Ubuntu 22.04
Description:
The following script:
CREATE ACCESS METHOD ham TYPE TABLE HANDLER heap_tableam_handler;
CREATE TABLE pt (a int) PARTITION BY LIST (a) USING ham;
DROP ACCESS METHOD ham;
ends successfully, with the access method dropped, though then:
CREATE TABLE tp1 PARTITION OF pt FOR VALUES IN (1);
fails with
ERROR: cache lookup failed for access method 16385
Whilst
CREATE TABLE t (a int) USING ham;
DROP ACCESS METHOD ham;
fails with
ERROR: cannot drop access method ham because other objects depend on it
DETAIL: table t depends on access method ham
HINT: Use DROP ... CASCADE to drop the dependent objects too.
Reproduced starting from 374c7a229.
