title: Postgres: More verbose error message: I am missing the table name
body: <p>I see this message:</p>
  
  <pre><code>IntegrityError: null value in column "date" violates not-null constraint
  DETAIL:  Failing row contains (10005, null, f, TEST, MAIL).
  </code></pre>
  
  <p>Is there a way to get a more verbose error message from PostgreSQL?</p>
  
  <p>I am missing the table name.</p>
