title: can we set more than one port in postgresql.config file?
body: <p>Im trying to remote connect MsSQL from PostgreSQL using Pg-admin, but every time i try to connect using dblink_connect function, im not able to connect and the Pg-admin throw the error : </p>
  
  <pre class="lang-none prettyprint-override"><code>ERROR:  could not establish connection
  DETAIL:  could not connect to server: Connection timed out (0x0000274C/10060)
      Is the server running on host "xxx.xxx.xxx.xxx" and accepting
      TCP/IP connections on port 5432?
  SQL state: 08001
  </code></pre>
  
  <p>The things I have tried:</p>
  
  <p>specify the port number in the connection string in db_link which is 8583 
    but it still throw the error as below </p>
  
  <pre><code>ERROR:  could not establish connection
  DETAIL:  server closed the connection unexpectedly
      This probably means the server terminated abnormally
      before or while processing the request.
  SQL state: 08001
  </code></pre>
  
  <p>changing the port in postgresql.conf file from 5432 to 8583 and restart, but it still throws error as below</p>
  
  <pre><code>ERROR:  could not establish connection

      TCP/IP connections on port 5432?
  SQL state: 08001
  </code></pre>
  
  <p>So, can I have more than one port number in the <code>postgresql.conf</code> file where hoping it will work that way.</p>
