title: PostgreSQL concat an int value with a numeric field
body: <p>I would like to do something like :</p>
  
  <pre><code>update cli_pe set nm_cli_espace_client = 9 || nm_cli_espace_client
   where nm_cli_pe = 7006488 
  </code></pre>
  
  <p><code>nm_cli_espace_client</code> is <code>numeric(0,8).</code></p>
