+  <para>
+   <command>ALTER MATERIALIZED VIEW</command> changes various auxiliary
+   properties of an existing materialized view.
+  </para>
+
+  <para>
+   You must own the materialized view to use <command>ALTER MATERIALIZED
+   VIEW</command>.  To change a materialized view's schema, you must also have
+   <literal>CREATE</literal> privilege on the new schema.
+   To alter the owner, you must also be a direct or indirect member of the new
+   owning role, and that role must have <literal>CREATE</literal> privilege on
+   the materialized view's schema.  (These restrictions enforce that altering
+   the owner doesn't do anything you couldn't do by dropping and recreating the
+   materialized view.  However, a superuser can alter ownership of any view
+   anyway.)
+  </para>
+
+  <para>
+   The statement subforms and actions available for
+   <command>ALTER MATERIALIZED VIEW</command> are a subset of those available
+   for <command>ALTER TABLE</command>, and have the same meaning when used for
+   materialized views.  See the descriptions for <xref linkend="sql-altertable"/>
+   for details.
