</pre></div><div class="refsect1" id="id-1.9.3.19.5"><h2>Description</h2><p>
<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 also be a direct or indirect member of 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 <code class="literal">DEPENDS ON EXTENSION</code> form marks the materialized view
as dependent on an extension, such that the materialized view will
automatically be dropped if the extension is dropped.
</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="xref" href="sql-altertable.html" title="ALTER TABLE"><span class="refentrytitle">ALTER TABLE</span></a>
for details.
