NAME

       CREATE_PUBLICATION - define a new publication

SYNOPSIS

       CREATE PUBLICATION name
           [ FOR TABLE [ ONLY ] table_name [ * ] [, ...]
             | FOR ALL TABLES ]
           [ WITH ( publication_parameter [= value] [, ... ] ) ]

DESCRIPTION

       CREATE PUBLICATION adds a new publication into the current database. The publication name must be
       distinct from the name of any existing publication in the current database.

       A publication is essentially a group of tables whose data changes are intended to be replicated through
       logical replication. See Section 31.1 for details about how publications fit into the logical replication
       setup.

PARAMETERS

       name
           The name of the new publication.

       FOR TABLE
           Specifies a list of tables to add to the publication. If ONLY is specified before the table name,
           only that table is added to the publication. If ONLY is not specified, the table and all its
           descendant tables (if any) are added. Optionally, * can be specified after the table name to
           explicitly indicate that descendant tables are included. This does not apply to a partitioned table,
           however. The partitions of a partitioned table are always implicitly considered part of the
           publication, so they are never explicitly added to the publication.

           Only persistent base tables and partitioned tables can be part of a publication. Temporary tables,
           unlogged tables, foreign tables, materialized views, and regular views cannot be part of a
           publication.

           When a partitioned table is added to a publication, all of its existing and future partitions are
           implicitly considered to be part of the publication. So, even operations that are performed directly
           on a partition are also published via publications that its ancestors are part of.

       FOR ALL TABLES
           Marks the publication as one that replicates changes for all tables in the database, including tables
           created in the future.

       WITH ( publication_parameter [= value] [, ... ] )
           This clause specifies optional parameters for a publication. The following parameters are supported:

           publish (string)
               This parameter determines which DML operations will be published by the new publication to the
               subscribers. The value is comma-separated list of operations. The allowed operations are insert,
               update, delete, and truncate. The default is to publish all actions, and so the default value for
               this option is 'insert, update, delete, truncate'.

           publish_via_partition_root (boolean)
               This parameter determines whether changes in a partitioned table (or on its partitions) contained
               in the publication will be published using the identity and schema of the partitioned table
               rather than that of the individual partitions that are actually changed; the latter is the
               default. Enabling this allows the changes to be replicated into a non-partitioned table or a
               partitioned table consisting of a different set of partitions.

               If this is enabled, TRUNCATE operations performed directly on partitions are not replicated.

NOTES

       If neither FOR TABLE nor FOR ALL TABLES is specified, then the publication starts out with an empty set
       of tables. That is useful if tables are to be added later.

       The creation of a publication does not start replication. It only defines a grouping and filtering logic
       for future subscribers.

       To create a publication, the invoking user must have the CREATE privilege for the current database. (Of
       course, superusers bypass this check.)

       To add a table to a publication, the invoking user must have ownership rights on the table. The FOR ALL
       TABLES clause requires the invoking user to be a superuser.

       The tables added to a publication that publishes UPDATE and/or DELETE operations must have REPLICA
       IDENTITY defined. Otherwise those operations will be disallowed on those tables.

       For an INSERT ... ON CONFLICT command, the publication will publish the operation that results from the
       command. Depending on the outcome, it may be published as either INSERT or UPDATE, or it may not be
       published at all.

       ATTACHing a table into a partition tree whose root is published using a publication with
       publish_via_partition_root set to true does not result in the table's existing contents being replicated.

       COPY ... FROM commands are published as INSERT operations.

       DDL operations are not published.

EXAMPLES

       Create a publication that publishes all changes in two tables:

           CREATE PUBLICATION mypublication FOR TABLE users, departments;

       Create a publication that publishes all changes in all tables:

           CREATE PUBLICATION alltables FOR ALL TABLES;

       Create a publication that only publishes INSERT operations in one table:

           CREATE PUBLICATION insert_only FOR TABLE mydata
               WITH (publish = 'insert');

COMPATIBILITY

       CREATE PUBLICATION is a PostgreSQL extension.
