我将 django 版本从 1.7.5 升级到 1.9.2。所有迁移都运行了，但是当我运行测试时，我得到了以下错误。

django.db.utils.ProgrammingError: relation "django_content_type" does not exist

我检查了数据库并且存在 django_content_type 模型。我正在使用 PostgreSQL。

我只在 PostgreSQL 上而不是在 Sqlite3 上收到此错误。

我在旧 Django 版本中使用了 uuid 字段和 JSON 字段，但在新版本中，这些字段是 django 模型默认提供的。所以我用 django 默认字段替换了这些字段并再次创建了迁移....

现在它的工作没有任何问题..
