Postgresql HStore, JSON data-type and Arrays with Peewee ORM

I've developed an interest in some of the more advanced features of SQLite after reading the O'Reilly title Using SQLite (Small. Fast. Reliable. Choose Any Three).

Because peewee supports both of these databases (as well as MySQL), it is limited to a lowest-common-denominator feature set. While this encompasses a broad range of features, each database engine has its own extensions and I've been interested in adding some pythonic support for the cooler extensions.

To follow along at home, feel free to install peewee:

pip install peewee
