title: Stop .filter() on first match in Django with Postgres
body: <p>Is there a way to stop querying the remaining records in the database after the query returns a match.</p>
  
  <p>For instance if I do this:</p>
  
  <pre><code>Profile.objects.filter(first_name='Dwight')
  </code></pre>
  
  <p>I want it to stop running the query for all the Profiles as soon as it finds a <code>Profile</code> with the <code>first_name</code> of <strong>Dwight</strong>. </p>
