我无法通过pgadmin创建我的postgresql数据库，但我经历了很多过程，但无法修复，我的操作系统是Manjaro KDE'ARCH LINUX'
并且当我要创建服务器时错误显示如下我不知道到底是什么问题
could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting

是这样我不知道是什么问题吗？请帮助我解决这个问题
PgAdmin4的“ create-> server ...”选项不会自行创建PostgreSQL服务器，它会创建一条记录，允许PgAdmin4连接到现有的并正在运行的服务器。
