ALTER PUBLICATION(7) PostgreSQL 15.7 Documentation ALTER PUBLICATION(7)
NAME
ALTER_PUBLICATION - change the definition of a publication
SYNOPSIS
ALTER PUBLICATION name ADD publication_object [, ...]
ALTER PUBLICATION name SET publication_object [, ...]
ALTER PUBLICATION name DROP publication_object [, ...]
ALTER PUBLICATION name SET ( publication_parameter [= value] [, ... ] )
ALTER PUBLICATION name OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }
ALTER PUBLICATION name RENAME TO new_name
where publication_object is one of:
TABLE [ ONLY ] table_name [ * ] [ ( column_name [, ... ] ) ] [ WHERE ( expression ) ] [, ... ]
TABLES IN SCHEMA { schema_name | CURRENT_SCHEMA } [, ... ]
DESCRIPTION
The command ALTER PUBLICATION can change the attributes of a
publication.
The first three variants change which tables/schemas are part of the
publication. The SET clause will replace the list of tables/schemas in
the publication with the specified list; the existing tables/schemas
that were present in the publication will be removed. The ADD and DROP
clauses will add and remove one or more tables/schemas from the
publication. Note that adding tables/schemas to a publication that is
already subscribed to will require an ALTER SUBSCRIPTION ... REFRESH
PUBLICATION action on the subscribing side in order to become
effective. Note also that DROP TABLES IN SCHEMA will not drop any
schema tables that were specified using FOR TABLE/ ADD TABLE, and the
combination of DROP with a WHERE clause is not allowed.
The fourth variant of this command listed in the synopsis can change
all of the publication properties specified in CREATE PUBLICATION
(CREATE_PUBLICATION(7)). Properties not mentioned in the command retain
their previous settings.
The remaining variants change the owner and the name of the
publication.
You must own the publication to use ALTER PUBLICATION. Adding a table
to a publication additionally requires owning that table. The ADD
TABLES IN SCHEMA and SET TABLES IN SCHEMA to a publication requires the
invoking user to be a superuser. To alter the owner, you must also be a
direct or indirect member of the new owning role. The new owner must
have CREATE privilege on the database. Also, the new owner of a FOR ALL
TABLES or FOR TABLES IN SCHEMA publication must be a superuser.
However, a superuser can change the ownership of a publication
regardless of these restrictions.
Adding/Setting any schema when the publication also publishes a table
with a column list, and vice versa is not supported.
PARAMETERS
name
The name of an existing publication whose definition is to be
altered.
table_name
Name of an existing table. If ONLY is specified before the table
name, only that table is affected. If ONLY is not specified, the
table and all its descendant tables (if any) are affected.
Optionally, * can be specified after the table name to explicitly
indicate that descendant tables are included.
Optionally, a column list can be specified. See CREATE PUBLICATION
(CREATE_PUBLICATION(7)) for details. Note that a subscription
having several publications in which the same table has been
published with different column lists is not supported. See
Warning: Combining Column Lists from Multiple Publications for
details of potential problems when altering column lists.
If the optional WHERE clause is specified, rows for which the
expression evaluates to false or null will not be published. Note
that parentheses are required around the expression. The expression
is evaluated with the role used for the replication connection.
schema_name
Name of an existing schema.
SET ( publication_parameter [= value] [, ... ] )
This clause alters publication parameters originally set by CREATE
PUBLICATION (CREATE_PUBLICATION(7)). See there for more
information.
new_owner
The user name of the new owner of the publication.
new_name
The new name for the publication.
EXAMPLES

ALTER PUBLICATION noinsert SET (publish = 'update, delete');

ALTER PUBLICATION mypublication ADD TABLE users (user_id, firstname), departments;
Change the set of columns published for a table:
ALTER PUBLICATION mypublication SET TABLE users (user_id, firstname, lastname), TABLE departments;
Add schemas marketing and sales to the publication sales_publication:
ALTER PUBLICATION sales_publication ADD TABLES IN SCHEMA marketing, sales;
