PostgreSQL for Django on Elastic Beanstalk
Postgre is now selectable from the AWS RDS configurations.  Validated through Elastic Beanstalk application setup 2014-01-27.
I'm reading conflicting reports about using PostgreSQL on Amazon's Elastic Beanstalk for python (Django).  
Some sources say it isn't possible: (http://www.forbes.com/sites/netapp/2012/08/20/amazon-cloud-elastic-beanstalk-paas-python/).  I've been through a dummy app setup, and it does seem that MySQL is the only option (amongst other ones that aren't Postgres).
However, I've found fragments around the place mentioning that it is possible - even if they're very light on detail.
I need to know the following:

Is it possible to run a PostgreSQL database with a Django app on Elastic Beanstalk?
If it's possible, is it worth the trouble?
If it's possible, how would you set it up?
