title: set auto increment initial value for id in django model
body: <p>i have a model with just one field.
  name.</p>
  
  <pre><code>class City(models.Model): &lt;br&gt;
      name = models.CharField(max_length=30)
  </code></pre>
  
  <p>Django sets <code>id</code> by itself so I end up with <code>id</code> and a <code>description</code> field in SQL.</p>
  
  <p>but that <code>id</code> field is always increment by 1. 
  I want to start it from 1000 and then increment by one.</p>
  
  <p>Is there any way to do this in Django?</p>
