Question

我安装了PostgreSQL，但是当我在Windows CMD中运行命令postgres

时

它出现以下错误：

postgres does not know where to find the server configuration file.
You must specify the --config-file or -D invocation option or set the PGDATA environment variable.

即使在运行命令

之后

initdb postgres维持similar Issue
postgres -D C:\Program Files\PostgreSQL\data\ 给了我以下输出：

Answer 1

如错误所示，要启动postgresql集群，您必须设置数据文件夹的路径。可能类似于：

pg_ctl

但建议使用postgres代替pg_ctl -D "C:\Program Files\PostgreSQL\data\" start：

Is another postmaster already running on port 5432?

不要忘记查看有关how to start a server和how to use pg_ctl的postgres文档。

通常，postgres安装程序会创建一个服务/守护程序，因此无需手动启动服务器。所以，如果你收到像

这样的错误

psql

这可能意味着服务器已在运行。尝试使用override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

连接到它

postgres不知道在哪里可以找到服务器配置文件
