title: How to empty sqlite3 database in django
body: <p>Running through the polls tutorial I ran this line:</p>
  
  <pre><code>q = Question(question_text="What's new?", pub_date=timezone.now())
  </code></pre>
  
  <p>Now, I've already ran:</p>
  
  <pre><code>python manage.py flush
  </code></pre>
  
  <p>But when I save and check the ID, I noticed that the id is still incrementing.</p>
  
  <pre><code>&gt;&gt;&gt; q.save()
  &gt;&gt;&gt;q.id
  3
  </code></pre>
  
  <p>Why is the id value not 1? Why are the id values preserved even though the db was destroyed? </p>
