## ALTER PUBLICATION

ALTER PUBLICATION — change the definition of a publication

## Synopsis

    ALTER PUBLICATION name ADD TABLE [ ONLY ] table_name [ * ] [, ...]
    ALTER PUBLICATION name SET TABLE [ ONLY ] table_name [ * ] [, ...]
    ALTER PUBLICATION name DROP TABLE [ ONLY ] table_name [ * ] [, ...]
    ALTER PUBLICATION name SET ( publication_parameter [= value] [, ... ] )
    ALTER PUBLICATION name OWNER TO { new_owner | CURRENT_USER | SESSION_USER }
    ALTER PUBLICATION name RENAME TO new_name

## Description

The command `ALTER PUBLICATION` can change the attributes of a publication.

The first three variants change which tables are part of the publication. The `SET TABLE` clause will replace the list of tables in the publication with the specified one. The `ADD TABLE` and `DROP TABLE` clauses will add and remove one or more tables from the publication. Note that adding tables to a publication that is already subscribed to will require a `ALTER SUBSCRIPTION ... REFRESH PUBLICATION` action on the subscribing side in order to become effective.

The fourth variant of this command listed in the synopsis can change all of the publication properties specified in CREATE PUBLICATION. 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. 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` publication must be a superuser. However, a superuser can change the ownership of a publication regardless of these restrictions.

## 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.

`SET ( `publication_parameter` [= `value`] [, ... ] )`

  This clause alters publication parameters originally set by CREATE PUBLICATION. 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

Change the publication to publish only deletes and updates:

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

Add some tables to the publication:

    ALTER PUBLICATION mypublication ADD TABLE users, departments;

## Compatibility

`ALTER PUBLICATION` is a PostgreSQL extension.
