[sqlalchemy] Re: Differentiate what raised IntegrityError (fkey not found vs. duplicate pkey)

Mike will probably chime in with a more correct answer, but... You should be able to figure that out by catching the `sqlalchemy.exc.IntegrityError` error and inspecting the attributes (original error or the text message).
