Question

我最近使用适用于Linux的Windows子系统（WSL）在Windows 10上全新安装了Ubuntu 18.04。然后，我安装了PostgreSQL 10，并且能够成功启动数据库服务器。然后，我通过PGAdmin 4.4登录到服务器，并安装了PostGIS 2.5.2扩展。然后，当PGAdmin表示已失去与PostgreSQL服务器的连接时，我正要通过pg_restore导入数据。我尝试重新启动，但日志中出现以下错误：

我尝试重新安装Ubuntu 18.04和PostgreSQL 10，再次发生了同样的事情！我以前安装过上述安装程序，但工作正常。是否有人对导致此问题的原因有任何建议？

更新：A回答了以下问题。

Answer 1

因此，在进行了一些进一步的研究之后，我发现随着最新的PostgreSQL更新，先前的“无法刷新脏数据”警告已升级为“紧急情况”，我通过保留fsync = on并将data_sync_retry = true添加到postgresql.conf来解决了该问题。。我希望这对遇到相同问题的其他人很有用。看来问题是已知的，以后会解决，请参见https://github.com/Microsoft/WSL/issues/645。

Answer 2

WSL似乎不支持PostgreSQL所需的所有系统调用。您是否尝试安装Windows版本？您可以在这里获得它：
