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.

           Only persistent base tables can be part of a publication. Temporary tables, unlogged
           tables, foreign tables, materialized views, regular views, and partitioned tables
           cannot be part of a publication. To replicate a partitioned table, add the individual
           partitions to the publication.

       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'.

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
       actually results from the command. So depending of the outcome, it may be published as
       either INSERT or UPDATE, or it may not be published at all.

       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.
