Использование PostgreSQL с App Engine Standard

0 голосов
/ 26 сентября 2018

Я пытаюсь использовать postgres на стандартном движке приложения со средой python2.7.

Я использую sqlalchemy + pg8000 для подключения, строка подключения выглядит следующим образом: 

postgresql+pg8000://user:password@/dbname?unix_sock=/cloudsql/project:us-central1:db

Работает на локальноммашина, но при развертывании я получаю сообщение об ошибке: 

AttributeError: 'Connection' object has no attribute '_usock'

Как настроить соединение с базой данных?
