title: what should be put into the option default for the type array
body: <p>I've started working with the type array of doctrine, but I got a problem with it when I tried to define a default value. I've put <code>array(un, deux, trois)</code> but this created it as it is in my postgresql db and not serialized as mentioned into the doc.</p>
  
  <p>In the other hand, I don't think it's relevent to put the serialized value of my default value manually.</p>
  
  <p>has anyone used this type before? anyhelp? thanks</p>
