title: Defining default @GeneratedValue Strategy for Symfony MakerBundle
body: <p>When using the MakerBundle in Symfony (4) to create new entity (<code>make:entity EntityName</code>), an id is generated by default with annotation (if annotations enabled) <code>@GeneratedValue</code>.</p>
  
  <p><code>@GeneratedValue</code> means <code>@GeneratedValue(strategy="AUTO")</code>.</p>
  
  <p>According to the <a href="https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/basic-mapping.html#identifiers-primary-keys" rel="nofollow noreferrer">Doctrine documentation</a>, the <code>AUTO</code> strategy is supposed to use <strong>SERIAL</strong> type for the id in PostgreSQL. But, I do not know why in my case, the <code>AUTO</code> strategy use SEQUENCE for the id.</p>
  
  <p>Then, I can force it to use SERIAL by changing by hand into <code>@GeneratedValue(strategy="IDENTITY")</code> which means using <strong>SERIAL</strong> type in PostgreSQL.</p>
  
  <p>Is there any way to change the default @GeneratedValue annotation created by the MakerBundle for the new entities to be created with the <code>@GeneratedValue(strategy="IDENTITY")</code> annotation ?</p>
