Usando proteus el fallo es similar:
> config =
> config.set_trytond('postgresql://tryton:my_password_...@localhost:5432/ejemplo')
>
> /usr/local/lib/python2.7/dist-packages/proteus/config.pyc in
> set_trytond(database, user, language, password, config_file)
> 266 'Set trytond package as backend'
> 267 _CONFIG.current = TrytondConfig(database, user,
> language=language,
> --> 268 password=password, config_file=config_file)
> 269 return _CONFIG.current
> 270
>
> /usr/local/lib/python2.7/dist-packages/proteus/config.pyc in
> __init__(self, database, user, language, password, config_file)

y siguiendo la pista al fallo veo que al parsear la uri:
/usr/local/lib/python2.7/dist-packages/proteus/config.py
> if database:
> uri = urlparse.urlparse(database)
> database_name = uri.path.strip('/')
> if not database_name:
> database_name = os.environ['DB_NAME']
> self.database_name = database_name
> self._user = user
> self.config_file = config_file
>
> Pool.start()
> self.pool = Pool(database_name)
> self.pool.init()
>
> with Transaction().start(self.database_name, 0) as transaction:
después de la línea
> uri = urlparse.urlparse(database)
uri.scheme tiene el valor correcto 'postgresql', pero no se usa antes de
ejecutar:
> Transaction().start(self.database_name, 0)
que es donde aparece el error al intentar conectar a la inexistente base
de datos sqlite.
