从PostgreSQL 9.6
升级到PostgreSQL 10
后,在使用的过程中,过去的pgAdmin 3
出现了很多问题,无法完全支持PostgreSQL 10
。pgAdmin 4
体验差,很糟糕就算了,关键是postgresql-10.3-1-windows-binaries
压缩版中的pgAdmin 4
无法启动,启动的时候会报出如下错误信息:The application server could not be contacted
解决办法:在·venv\lib\site-packages\backports·目录下创建一个空的__init__.py
cd pgAdmin 4
type nul > venv\lib\site-packages\backports\__init__.py
