我有一个在Windows 7上运行的Postgres 9.2作为服务。 每天数据库似乎停止，有时它开始单独运行，有时我需要重新启动服务。 没有太多的日志信息，我没有安装在这台电脑上的防病毒，防火墙。 我试图改善日志信息，但没有多大帮助。
我无法在Internet上find同样的问题，或者在serverfault上找不到这个问题。
有一些日志信息：

有小费吗？
谢谢
首先，在台式机上运行生产服务器，这是一个不好的做法。 我build议你迁移一个服务器的操作系统，如Windows服务器，Linux等的专用服务器。
关于您的错误[1] ，看起来像您遇到networking错误：
拒绝连接。
目标计算机主动拒绝，因此无法build立连接。 这通常是由于尝试连接到外部主机上处于非活动状态的服务（即没有运行服务器应用程序的服务）所致。
看看这里[2]了解更多细节。
如果您已经放弃解决您的networking问题，请考虑我的build议。
希望能帮助到你。
