I have replication slot which I want to delete but when I do delete I got an error that I can't delete from view. Any ideas?
postgres=# SELECT * FROM pg_replication_slots ;
slot_name | plugin | slot_type | datoid | database | active | xmin | catalog_xmin | restart_lsn
--------------+--------------+-----------+--------+----------+--------+------+--------------+-------------
bottledwater | bottledwater | logical | 12141 | postgres | t | | 374036 | E/FE8D9010
(1 row)
postgres=# delete from pg_replication_slots;
ERROR: cannot delete from view "pg_replication_slots"
DETAIL: Views that do not select from a single table or view are not automatically updatable.
HINT: To enable deleting from the view, provide an INSTEAD OF DELETE trigger or an unconditional ON DELETE DO INSTEAD rule.
postgres=#
Use pg_drop_replication_slot
:
select pg_drop_replication_slot('bottledwater');
The replication slot must be inactive, i.e. no active connections. So if there's a streaming replica using the slot you must stop the streaming replica. Or you can change its recovery.conf
so it doesn't use a slot anymore and restart it.
