May I alter SERVER for foreign table?
<p>According to the <a href="http://www.postgresql.org/docs/9.5/static/sql-alterforeigntable.html" rel="noreferrer">DOC</a> I can not do that. But fully recreate table force me to do huge work instead of simple:</p>

<pre><code>ALTER FOREIGN TABLE table_name ALTER SERVER new_server_name;
</code></pre>
