Django/PostgreSQL - 错误地配置错误

Question

我使用PostgreSQL开始了一个Django项目，它在安装完成后工作正常，我可以添加东西到数据库，在管理员等中查看。作为Postgres的新手，我认为这将是一个很好的主意退出终端，看它是否会在重新启动时自动连接到数据库（就像SQLite一样）。但是现在它抛出这个错误：

当导入psycopg2没有错误，psql的壳里面，如果我键入\c它说我已经连接到服务器“凯尔”（在我的Django的指定我的服务器名称设置）为用户'Kyle'（同样在设置中指定）。

注：全部采用最新版本的一切

我觉得这是一个依赖的问题，因为我意识到我是不是在我的虚拟环境（它的工作原理，当我在它是）。
