title: Maximum characters in labels (table names, columns etc)
body: <p>Hope this question wasn't asked before. Does anyone know the character limit for domain names?
  For example if I write this:</p>
  
  <pre><code>CREATE DOMAIN d_complement_activite_etablissement AS character varying
  </code></pre>
  
  <p>it will create a domain with the name:</p>
  
  <pre><code>d_complement_activite_etabliss
  </code></pre>
  
  <p>(Yeah, I know how to count, but I want some more info on the subject).</p>
  
  <p>Is there a command that can change this maximum length? Is this length the same for other names (columns, tables etc)?</p>
