我有复制插槽,我想删除,但当我删除我有一个错误,我无法从视图中删除.有任何想法吗?
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=#
使用pg_drop_replication_slot:
select pg_drop_replication_slot('bottledwater');

复制槽必须是非活动的,即没有活动的连接.所以如果有一个流复制使用插槽,你必须停止流复制.或者您可以更改其recovery.conf,以便不再使用插槽并重新启动它.
