(Comment from a bystander). You probably want aiopg in order to maintain the async characteristics and use the "friendly" asyncio syntax.
There is also peewee-async (http://peewee-async.readthedocs.io/en/latest/) if you want an ORM using asyncio. (I've been meaning to try this myself, but haven't had an opportunity).
absolutely.. i am concerned about frameworks not fundamentally thinking about DB. With async, there is that additional problem of "this does not work in async mode". So I would hope the developers include database hookup as part of their unit test suite.
