DROP SUBSCRIPTION(7)     PostgreSQL 16.2 Documentation    DROP SUBSCRIPTION(7)

NAME
       DROP_SUBSCRIPTION - remove a subscription

SYNOPSIS
       DROP SUBSCRIPTION [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION
       DROP SUBSCRIPTION removes a subscription from the database cluster.

       To execute this command the user must be the owner of the subscription.

       DROP SUBSCRIPTION cannot be executed inside a transaction block if the
       subscription is associated with a replication slot. (You can use ALTER
       SUBSCRIPTION to unset the slot.)

PARAMETERS
       name
           The name of a subscription to be dropped.

       CASCADE
       RESTRICT
           These key words do not have any effect, since there are no
           dependencies on subscriptions.

NOTES
       When dropping a subscription that is associated with a replication slot
       on the remote host (the normal state), DROP SUBSCRIPTION will connect
       to the remote host and try to drop the replication slot (and any
       remaining table synchronization slots) as part of its operation. This
       is necessary so that the resources allocated for the subscription on
       the remote host are released. If this fails, either because the remote
       host is not reachable or because the remote replication slot cannot be
       dropped or does not exist or never existed, the DROP SUBSCRIPTION
       command will fail. To proceed in this situation, first disable the
       subscription by executing ALTER SUBSCRIPTION ... DISABLE, and then
       disassociate it from the replication slot by executing ALTER
       SUBSCRIPTION ... SET (slot_name = NONE). After that, DROP SUBSCRIPTION
       will no longer attempt any actions on a remote host. Note that if the
       remote replication slot still exists, it (and any related table
       synchronization slots) should then be dropped manually; otherwise
       it/they will continue to reserve WAL and might eventually cause the
       disk to fill up. See also Section 31.2.1.

       If a subscription is associated with a replication slot, then DROP
       SUBSCRIPTION cannot be executed inside a transaction block.

EXAMPLES

           DROP SUBSCRIPTION mysub;
