我刚刚在我的新 Mac mini 上安装了 Postgresql Server、PGAdmin、Stack Tools。在我的 MacBook 上，我有一个 postgresql 服务器图标，显示所有服务器。 (我的 Mac mini 上缺少此功能)

PGAdmin 正在运行。

Answer 1

作为您在 application.yml 文件中发布的示例，您没有指定密码:

test:
 adapter: postgresql
 encoding: unicode
 database: pcms_test
 host: localhost
 pool: 5
 username: postgres
 password: 

您需要为您的 postgres 用户设置密码并将该密码放在您的database.yml 中才能解决问题
