django - 在 centos 中使用 postgresql 迁移 Kiwi 时出错

Question

当我在 centos6 中使用 postgresql 中的 python3.6 加载 Kiwi 数据库模式时，出现以下编程错误 django.db.utils.ProgrammingError: syntax error at or near "WITH ORDINALITY"
LINE 6:

The above exception was the direct cause of the following exception:

我发现我的情况是什么问题。我安装了与 django2.4 不兼容的 PostgreSQL 服务器版本(9.2)。在我用 PostgreSQL 10 替换它之后，它运行良好。
