請幫我如果您需要有關這些錯誤，那麼PLZ告知任何進一步的信息解決這個錯誤..

。

謝謝。

Answer 1

PostgreSQL有兩種認證模式。一種是通過Unix套接字認證，這意味着PostgreSQL檢查連接到PostgreSQL的進程的用戶，然後檢查該用戶是否有權訪問數據庫。這種認證模式是您通過pg命令從命令行訪問PostgreSQL時通常使用的模式。

第二個是您已經熟悉的基於密碼的身份驗證。

看起來你沒有爲「postgres」用戶正確設置密碼認證。最重要的是，您的應用程序以「nobody」用戶身份運行，因此PostgreSQL無法通過Unix套接字對您的應用程序進行身份驗證。

解決方法是製作一個PostgreSQL用戶名/密碼認證條目，並將其填充到您的database.yml中。
