"""
This is the core database connection.
All CMS code assumes database SELECT statements cast the resulting values as such:
* booleans are mapped to Python booleans
* dates are mapped to Python datetime.date objects
* times are mapped to Python datetime.time objects
* timestamps are mapped to Python datetime.datetime objects
Right now, we're handling this by using psycopg's custom typecast definitions.
If we move to a different database module, we should ensure that it either
performs the appropriate typecasting out of the box, or that it has hooks that
let us do that.
