title: stale content types while syncdb in Django
body: <p>While I'm trying to <code>syncdb</code> for my django project, I'm seeing following complains:</p>
  
  <pre><code>The following content types are stale and need to be deleted:
  
  myapp | 
  
  Any objects related to these content types by a foreign key will also
  be deleted. Are you sure you want to delete these content types?
  If you're unsure, answer 'no'.
  </code></pre>
  
  <p>While I've also read the similar problem <a href="https://stackoverflow.com/questions/5510843/django-syncdb-incorrectly-warns-that-many-to-many-field-is-stale">django-syncdb-many-to-many-stale</a>, but I cannot risk myself typing <code>yes</code> since I'm on prod instance.</p>
  
  <p>Would <code>yes</code> <strong>safely</strong> delete those stale entries in contenttype?</p>
