DROP SUBSCRIPTION(7) PostgreSQL 18.6 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 sub- scription is associated with a replication slot. (You can use ALTER SUB- SCRIPTION to unset the slot.) PARAMETERS IF EXISTS Do not throw an error if the subscription does not exist. A notice is issued in this case. 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 re- leased. 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 execut- ing ALTER SUBSCRIPTION ... SET (slot_name = NONE). After that, DROP SUB- SCRIPTION will not attempt to drop the subscription's own replication slot. It may still connect to the publisher to drop internally-created table syn- chronization slots if some table synchronization is left unfinished; if the publisher is unreachable, those slots (and the main slot, if it still ex- ists) must be dropped manually. Otherwise it/they will continue to reserve WAL and might eventually cause the disk to fill up. See also Sec- tion 29.2.1. If a subscription is associated with a replication slot, then DROP SUB- SCRIPTION cannot be executed inside a transaction block.
