Postgres 无法启动（Windows）

Question

这是我经常遇到的问题。

Postgresql 随机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。 当服务启动时，我有以下日志：

2017-08-27 19:52:17 -03 FATAL:  the database system is starting up
2017-08-27 19:52:17 -03 LOG:  database system was interrupted; last known up at 2017-08-27 18:17:21 -03

2017-08-27 19:52:19 -03 LOG:  autovacuum launcher started

我有 i7、8GB 和 Windows 10。今天我使用 Postgresql 9.6

我已经安装了不同版本的Postgresql（9.4、9.5），但是我无法解决。

有人有解决问题的想法吗？

错误前的日志：

我看到它在 Windows 10 上发生超过 3 次，所以... 在我的 Windows 10 中，我遇到了这个问题，我删除了文件“postmaster.pid”。一个工作的兄弟告诉我这样做，我不知道为什么但它解决了。 服务无法启动的另一个原因是“Warsaw”安全模块（由银行使用），如果您已在计算机上安装它或类似的东西，请尝试卸载并重新启动系统。 希望对大家有所帮助?
