Should support Postgres as well as MySQL #186
Description
Hey guys! I love this repository, it has helped me significantly.
The issue I am facing is all of the MySQL add-ons for Heroku limit the storage to 5MB which is obviously very little and can at most handle 1 blog post. The Heroku Postgres add-on allows up to 1GB for free so I am wondering if we can build out the functionality to support Postgres as well as MySQL so that we can remain in the free DB tier.
I have created this issue and I am willing to implement the changes as well.
