Question

我使用PostgreSQL创建了一个Django项目，它在设置后工作正常，我可以在数据库中添加内容，在管理员中查看等等。作为Postgres的新手，我认为退出终端是个好主意看看它是否会在重启时“自动连接”到数据库（就像SQLite一样）。但是现在它抛出了这个错误：

导入psycopg2时没有错误，如果我输入\c，则在psql shell内部显示我已连接到服务器'Kyle'（我的django设置中指定的服务器名称）为User'Kyle' （也在设置中指定）。

注意：使用所有最新版本

我认为这是一个依赖性问题，因为我意识到我不在我的虚拟环境中（当我进入它时它会起作用）。
