  28.    <code class="command">ALTER MATERIALIZED VIEW</code> changes various auxiliary

  29.    properties of an existing materialized view.

  30.   </p><p>

  31.    You must own the materialized view to use <code class="command">ALTER MATERIALIZED

  32.    VIEW</code>.  To change a materialized view's schema, you must also have

  33.    <code class="literal">CREATE</code> privilege on the new schema.

  34.    To alter the owner, you must also be a direct or indirect member of the new

  35.    owning role, and that role must have <code class="literal">CREATE</code> privilege on

  36.    the materialized view's schema.  (These restrictions enforce that altering

  37.    the owner doesn't do anything you couldn't do by dropping and recreating the

  38.    materialized view.  However, a superuser can alter ownership of any view

  39.    anyway.)

  40.   </p><p>

  41.    The <code class="literal">DEPENDS ON EXTENSION</code> form marks the materialized view

  42.    as dependent on an extension, such that the materialized view will

  43.    automatically be dropped if the extension is dropped.

  44.   </p><p>

  45.    The statement subforms and actions available for

  46.    <code class="command">ALTER MATERIALIZED VIEW</code> are a subset of those available

  47.    for <code class="command">ALTER TABLE</code>, and have the same meaning when used for

  48.    materialized views.  See the descriptions for <a class="xref" href="sql-altertable.html" title="ALTER TABLE"><span class="refentrytitle">ALTER TABLE</span></a>

  49.    for details.
