无法连接 PostgreSQL 服务器

Question

当我尝试连接到 PostgreSQL 时，我收到以下消息：

Unable to connect to server:
could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?

当我安装 PostgreSQL 时，我得到了错误：

Problem running post-install step. Installation may not complete correctly. The database cluster initialisation failed.

我的假设是，我有一些问题与data文件夹中的PostgreSQL，因为data文件夹为空。

该错误表明您刚刚安装了 postgres 软件并且没有对其进行配置。
