  <title>Description</title>

  <para>
   The first variant of this command listed in the synopsis can change
   all of the publication properties specified in
   <xref linkend="sql-createpublication">.  Properties not mentioned in the
   command retain their previous settings.  Database superusers can change any
   of these settings for any role.
  </para>

  <para>
   To alter the owner, you must also be a direct or indirect member of the new
   owning role. The new owner must have <literal>CREATE</literal> privilege on
   the database.  Also, the new owner of a <literal>FOR ALL TABLES</literal>
   publication must be a superuser.  However, a superuser can change the
   ownership of a publication while circumventing these restrictions.
  </para>

  <para>
   The other variants of this command deal with the table membership of the
   publication.  The <literal>SET TABLE</literal> clause will replace the
   list of tables in the publication with the specified one.
   The <literal>ADD TABLE</literal> and
   <literal>DROP TABLE</literal> will add and remove one or more tables from
   the publication.
