ALTER SUBSCRIPTION — change the definition of a subscription

   ALTER SUBSCRIPTION can change most of the subscription
   properties that can be specified
   in CREATE SUBSCRIPTION.
  
   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 DROP SUBSCRIPTION.
   Commands ALTER SUBSCRIPTION ... REFRESH PUBLICATION and
   ALTER SUBSCRIPTION ... {SET|ADD|DROP} PUBLICATION ...
   with refresh option as true cannot be
   executed inside a transaction block.
  
nameThe name of a subscription whose properties are to be altered.
CONNECTION 'conninfo'This clause alters the connection property originally set by CREATE SUBSCRIPTION. See there for more information.
SET PUBLICATION publication_nameADD PUBLICATION publication_nameDROP PUBLICATION publication_name
      Changes 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 CREATE SUBSCRIPTION
      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 the last invocation of REFRESH PUBLICATION or
      since CREATE SUBSCRIPTION.
     
      refresh_option specifies additional options for the
      refresh operation.  The supported options are:
      
copy_data (boolean)
          Specifies whether the existing data in the publications that are
          being subscribed to should be copied once the replication starts.
          The default is true.  (Previously subscribed
          tables are not copied.)
         
ENABLEEnables the previously disabled subscription, starting the logical replication worker at the end of transaction.
DISABLEDisables the running subscription, stopping the logical replication worker at the end of transaction.
SET ( subscription_parameter [= value] [, ... ] )
      This clause alters parameters originally set by
      CREATE SUBSCRIPTION.  See there for more
      information.  The parameters that can be altered
      are slot_name,
      synchronous_commit,
      binary, and
      streaming.
     
new_ownerThe user name of the new owner of the subscription.
new_nameThe 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.
