+ <code class="command">ALTER MATERIALIZED VIEW</code> changes various auxiliary
+ properties of an existing materialized view.
+ </p><p>
+ You must own the materialized view to use <code class="command">ALTER MATERIALIZED
+ VIEW</code>. To change a materialized view's schema, you must also have
+ <code class="literal">CREATE</code> privilege on the new schema.
+ To alter the owner, you must be able to <code class="literal">SET ROLE</code> to the
+ new owning role, and that role must have <code class="literal">CREATE</code>
+ 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.)
+ </p><p>
+ The statement subforms and actions available for
+ <code class="command">ALTER MATERIALIZED VIEW</code> are a subset of those available
+ for <code class="command">ALTER TABLE</code>, and have the same meaning when used for
+ materialized views. See the descriptions for
+ <a class="link" href="sql-altertable.html" title="ALTER TABLE"><code class="command">ALTER TABLE</code></a>
+ for details.
