title: Postgresql config parameters not reflecting even after service restart
body: <p>I changed </p>
  
  <pre><code>  client_min_messages =  warning
  </code></pre>
  
  <p>in postgresql.conf file. </p>
  
  <p>I have restarted service after this change. 
  But when I fetch data using command </p>
  
  <pre><code>`select * from pg_settings where name  = 'client_min_messages'` 
  </code></pre>
  
  <p>in pg_admin, it still shows <strong>notice</strong> instead of <strong>warning</strong>.</p>
  
  <p>below is the output of the query</p>
