David Lord:

When initializing a model, what is the correct value to pass to a range column?  Prompted by [this StackOverflow question](https://stackoverflow.com/questions/23563736/how-to-use-postgres-numeric-range-with-sqlalchemy), I looked at [the tests](https://bitbucket.org/zzzeek/sqlalchemy/src/55eacc8dbea3c3f98197bde9034fd6558fb2bc09/test/dialect/postgresql/test_types.py?at=master#cl-1589) and found they were using a [type helper from psycopg2](http://pythonhosted.org//psycopg2/extras.html#range-data-types).  Is that the proper way, or is there something on SQLAlchemy's side too?  Either way, it's not made clear in the docs.
