title: Symfony Doctrine-fixtures bundle, fail --purge-with-truncate
body: <p>Im using DoctrineFixturesBundle and trying to load fixtures</p>
  
  <pre><code>app/console -e=test doctrine:fixtures:load --purge-with-truncate
  </code></pre>
  
  <p>All data in postgres database.But why after --purge-with-truncate table sequence not restart, and just incriment with each fixture load?
  How i read in postgres truncate documentation </p>
  
  <pre><code>RESTART IDENTITY
  Automatically restart sequences owned by columns of the truncated table(s).
  </code></pre>
  
  <p>May be entities generated incorrect?</p>
