title: How to get doctrine to generate sql with BIGINT type?
body: <p>In my schema I have a number of field that need to be <code>BIGINT</code>. I use the following command from Symfony</p>
  <pre class="lang-bash prettyprint-override"><code>symfony doctrine:build-sql
  </code></pre>
  <p>to generate my database. The fields always come out as type <code>int</code>. I have tried the following types in the schema:</p>
  <ul>
  <li><code>int</code></li>
  <li><code>{type: integer, notnull: true}</code></li>
  <li><code>{type: integer(5), notnull: true}</code></li>
  <li><code>{type: bigint, notnull: true}</code></li>
  </ul>
  <p>None of them seem to work (I always rebuild the model before building the SQL).</p>
  <p>What type should i put in the <code>schema.yml</code>?</p>
