Question

当新版本出现时，我总是对PosgreSQL感到困扰。我再次尝试安装扩展插件plpython3u，并根据提示Error during: CREATE EXTENSION plpython3u; on PostgreSQL 9.6.0创建了扩展程序。我将目录添加到PATH，并将变量PYTHONHOME添加到环境。现在，当我尝试使用plpython3u创建任何简单函数时，它崩溃并显示信息

Connection to the server has been lost.

这是来自日志pgAdmin的文件的信息：

我正在使用由StackBuildier下载的EDB的FireFox for pgAdmin和Pyhton 有人知道如何正确安装吗？谢谢

Answer 1

经过10个小时的尝试，我决定安装Python 3.6.7，这对我来说并不常见，因为EDB支持3.6.5v，并且根据以前的经验，我认为较新的版本肯定行不通。

我错了。

我再次将Python36.dll（3.6.7v）复制到C：\ Windows \ System32，现在一切正常。

当我尝试使用plpython3u [WIN10，pgAdmin4 3.5]创建函数时，PosgreSQL 11失去了连接
