title: updating table with Postgresql Foreign data wrapper
body: <ol>
  <li><p>I created a foreign data wrapper table named <code>t_user</code> into <code>mySchema</code>.</p>
  
  <pre><code>IMPORT FOREIGN SCHEMA public LIMIT TO (t_user)
     FROM SERVER myServer INTO mySchema;
  </code></pre></li>
  <li><p>The <code>myServer</code> side <code>t_user</code> added some column, but the foreign table didn't update accordingly.</p></li>
  <li><p>I tried to delete the foreign table <code>t_user</code>, but it was used by my view and materialized view <code>t_user</code>, so the deletion failed.</p></li>
  </ol>
  
  <p>Any ideas on how to update this table?</p>
