title: Django JSONField dumping/loading
body: <p>I'm using JSONField in some of my Django models and would like to migrate this data from Oracle to Postgres. </p>
  
  <p>So far I haven't had any luck keeping this JSON data intact when using Django's dumpdata and loaddata commands, the data is transformed into string representations of the JSON. I've yet to find a good solution to this... Ideas?</p>
