这是我经常遇到的问题。
随机Postgresql停止并且不接收新连接（例如，pgAdmin，SQuirrel）。 我必须重新启动计算机几次，直到服务成功启动。 服务启动时，我有以下日志：
2017-08-27 19:52:17 -03 FATAL: the database system is starting up

我有i7,8GB和Windows 10.今天我使用的是Postgresql 9.6
我已经安装了不同版本的Postgresql（9.4,9.5），但我无法解决。
任何人都有解决问题的想法吗？

我看到它在Windows 10上发生了3次以上，所以... 在我的Windows 10中，我遇到了这个问题，并删除了文件“ postmaster.pid”。一个工作的兄弟告诉我去做，我不知道为什么，但是解决了。 服务无法启动的另一个原因是“华沙”安全模块（银行使用），如果您已经安装了安全模块或类似的东西，请尝试卸载并重新启动系统。 我希望它可以帮助某人
