I have faced the same issue.
Just change the port number 5432 to 5433 at postgresql.conf.
Restart your system.

我也遇到过同样的问题。在postgresql.conf中更改端口5432到5433。重新启动您的系统。

postgresql.conf file location in windows: C:\Program Files\PostgreSQL\9.4\data

postgresql。conf文件的位置在windows: c:)的程序文件。

Hope it will help you.
