psycopg2cffi driver inadvertently depends on psycopg2 also #403

Closed jamadden closed 4 years ago

jamadden commented 4 years ago

Because it inherits the check for the wait callback from psycopg2.

The error message we get is not at all clear about this, at least on Python 2. On Python 3, the cause of the DriverNotImportable exception should make this more clear, but we can probably do better.
