ALTER SUBSCRIPTION ALTER SUBSCRIPTION 7 SQL - Language Statements ALTER SUBSCRIPTION change the definition of a subscription ALTER SUBSCRIPTION name CONNECTION 'conninfo' ALTER SUBSCRIPTION name SET PUBLICATION publication_name [, ...] [ WITH ( publication_option [= value] [, ... ] ) ] ALTER SUBSCRIPTION name ADD PUBLICATION publication_name [, ...] [ WITH ( publication_option [= value] [, ... ] ) ] ALTER SUBSCRIPTION name DROP PUBLICATION publication_name [, ...] [ WITH ( publication_option [= value] [, ... ] ) ] ALTER SUBSCRIPTION name REFRESH PUBLICATION [ WITH ( refresh_option [= value] [, ... ] ) ] ALTER SUBSCRIPTION name ENABLE ALTER SUBSCRIPTION name DISABLE ALTER SUBSCRIPTION name SET ( subscription_parameter [= value] [, ... ] ) ALTER SUBSCRIPTION name OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER } ALTER SUBSCRIPTION name RENAME TO new_name ALTER SUBSCRIPTION can change most of the subscription properties that can be specified in . You must own the subscription to use ALTER SUBSCRIPTION. To alter the owner, you must also be a direct or indirect member of the new owning role. The new owner has to be a superuser. (Currently, all subscription owners must be superusers, so the owner checks will be bypassed in practice. But this might change in the future.) When refreshing a publication we remove the relations that are no longer part of the publication and we also remove the table synchronization slots if there are any. It is necessary to remove these slots so that the resources allocated for the subscription on the remote host are released. If due to network breakdown or some other error, PostgreSQL is unable to remove the slots, an error will be reported. To proceed in this situation, the user either needs to retry the operation or disassociate the slot from the subscription and drop the subscription as explained in . Commands ALTER SUBSCRIPTION ... REFRESH PUBLICATION and ALTER SUBSCRIPTION ... {SET|ADD|DROP} PUBLICATION ... with refresh option as true cannot be executed inside a transaction block. These commands also cannot be executed when the subscription has two_phase commit enabled, unless copy_data is false. See column subtwophasestate of pg_subscription to know the actual two-phase state. name The name of a subscription whose properties are to be altered. CONNECTION 'conninfo' This clause replaces the connection string originally set by . See there for more information. SET PUBLICATION publication_name ADD PUBLICATION publication_name DROP PUBLICATION publication_name These forms change the list of subscribed publications. SET replaces the entire list of publications with a new list, ADD adds additional publications to the list of publications, and DROP removes the publications from the list of publications. See for more information. By default, this command will also act like REFRESH PUBLICATION. publication_option specifies additional options for this operation. The supported options are: refresh (boolean) When false, the command will not try to refresh table information. REFRESH PUBLICATION should then be executed separately. The default is true. Additionally, the options described under REFRESH PUBLICATION may be specified, to control the implicit refresh operation. REFRESH PUBLICATION Fetch missing table information from publisher. This will start replication of tables that were added to the subscribed-to publications since CREATE SUBSCRIPTION or the last invocation of REFRESH PUBLICATION. refresh_option specifies additional options for the refresh operation. The supported options are: copy_data (boolean) Specifies whether to copy pre-existing data in the publications that are being subscribed to when the replication starts. The default is true. (Previously-subscribed tables are not copied.) ENABLE Enables a previously disabled subscription, starting the logical replication worker at the end of the transaction. DISABLE Disables a running subscription, stopping the logical replication worker at the end of the transaction. SET ( subscription_parameter [= value] [, ... ] ) This clause alters parameters originally set by . See there for more information. The parameters that can be altered are slot_name, synchronous_commit, binary, and streaming. new_owner The user name of the new owner of the subscription. new_name The new name for the subscription. Change the publication subscribed by a subscription to insert_only: ALTER SUBSCRIPTION mysub SET PUBLICATION insert_only; Disable (stop) the subscription: ALTER SUBSCRIPTION mysub DISABLE; ALTER SUBSCRIPTION is a PostgreSQL extension.
