NAME

6       DROP_SUBSCRIPTION - remove a subscription
7

SYNOPSIS

9       DROP SUBSCRIPTION [ IF EXISTS ] name [ CASCADE | RESTRICT ]
10

DESCRIPTION

12       DROP SUBSCRIPTION removes a subscription from the database cluster.
13
14       A subscription can only be dropped by a superuser.
15
16       DROP SUBSCRIPTION cannot be executed inside a transaction block if the
17       subscription is associated with a replication slot. (You can use ALTER
18       SUBSCRIPTION to unset the slot.)
19

PARAMETERS

21       name
22           The name of a subscription to be dropped.
23
24       CASCADE
25       RESTRICT
26           These key words do not have any effect, since there are no
27           dependencies on subscriptions.

NOTES

30       When dropping a subscription that is associated with a replication slot
31       on the remote host (the normal state), DROP SUBSCRIPTION will connect
32       to the remote host and try to drop the replication slot (and any
33       remaining table synchronization slots) as part of its operation. This
34       is necessary so that the resources allocated for the subscription on
35       the remote host are released. If this fails, either because the remote
36       host is not reachable or because the remote replication slot cannot be
37       dropped or does not exist or never existed, the DROP SUBSCRIPTION
38       command will fail. To proceed in this situation, disassociate the
39       subscription from the replication slot by executing ALTER SUBSCRIPTION
40       ... SET (slot_name = NONE). After that, DROP SUBSCRIPTION will no
41       longer attempt any actions on a remote host. Note that if the remote
42       replication slot still exists, it (and any related table
43       synchronization slots) should then be dropped manually; otherwise
44       it/they will continue to reserve WAL and might eventually cause the
45       disk to fill up. See also Section 31.2.1.
46
47       If a subscription is associated with a replication slot, then DROP
48       SUBSCRIPTION cannot be executed inside a transaction block.
