谢谢。PostgreSQL有两种身份验证模式。一种是通过Unix套接字身份验证，这意味着PostgreSQL检查连接到PostgreSQL的进程的用户，然后检查该用户是否有权访问数据库。当您通过
pg解决方案是创建一个PostgreSQL用户名/密码身份验证条目，并将其填入您的database.yml。请发布您的config/database.yml文件我发布我的config/database.yml文件。您正在使用相同的数据库进行开发和测试。在开发应用程序时，这可能会有问题。但我不知道这是你的连接问题的原因。首先登录到命令行客户端（psql），并确保您的凭据适用于数据库。之后，请参阅关于如何设置客户端身份验证文件，以便您可以使用localhost上的用户名/密码连接到该文件。您可以使用其他工具连接到数据库吗？
