Description

The commandALTER PUBLICATION can change the attributes of a publication.

The first three variants change which tables/schemas are part of the publication. TheSET 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. TheADD andDROP 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 anALTER SUBSCRIPTION ... REFRESH PUBLICATION action on the subscribing side in order to become effective. Note also thatDROP TABLES IN SCHEMA will not drop any schema tables that were specified usingFOR TABLE/ADD TABLE, and the combination ofDROP with aWHERE clause is not allowed.

The fourth variant of this command listed in the synopsis can change all of the publication properties specified inCREATE 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 useALTER PUBLICATION. Adding a table to a publication additionally requires owning that table. TheADD TABLES IN SCHEMA andSET TABLES IN SCHEMA to a publication requires the invoking user to be a superuser. To alter the owner, you must be able toSET ROLE to the new owning role, and that role must haveCREATE privilege on the database. Also, the new owner of aFOR ALL TABLES orFOR 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.
