<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.
</para>
