CREATE PUBLICATION — define a new publication
name[ FOR TABLE [ ONLY ]
table_name[ * ] [, ...] | FOR ALL TABLES ] [ WITH (
value] [, ... ] ) ]
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.
The name of the new publication.
Specifies a list of tables to add to the publication.
ONLY is specified before
the table name, only that table is added to the
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
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.

This clause specifies optional parameters for a publication. The following parameters are supported:
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
truncate. The default is to
publish all actions, and so the default value for
this option is
update, delete, truncate'.
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
ALL TABLES clause requires the invoking user to be a

actually results from the command. So depending of the outcome,
it may be published as either

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');
