   <command>ALTER SCHEMA</command> changes the definition of a schema.
  </para>

  <para>
   You must own the schema to use <command>ALTER SCHEMA</command>.
   To rename a schema you must also have the
   <literal>CREATE</literal> privilege for the database.
   To alter the owner, you must be able to <literal>SET ROLE</literal> to the
   new owning role, and that role must have the
   <literal>CREATE</literal> privilege for the database.
   (Note that superusers have all these privileges automatically.)
