Django can'；删除/创建数据库后的同步数据库

我想重置一个数据库，并发出了一个drop database命令，后跟一个create database命令 在postgresql服务器上，django应用程序通过psycopg2访问

当我执行./manage.py syncdb时，我得到以下错误：

我怎样才能解决这个问题呢？

试着像./manage.py重置你的应用程序那样重置你的数据库

我遇到了同样的问题，并在django mingus上的2979ea3d4541f7b3c51c17e160bc95b468ac99b处跟踪到提交

如果重置回提交2f7eb8de7e2cb1c776e801a40f008048fcbb6d36，同步应该会正常进行。

原因是django Mingus使用的django请求中存在问题。在syncdb期间，Django进行了一些db自省，相关的导入引发了此异常。如果您要从django request或django mingus中提取最新的位，您就可以了。

mySQL在遇到错误时不会使当前事务失效，其中postgres会抛出错误，并且在当前事务未中止之前不会运行其他查询。在这种情况下，您必须终止该事务或使用该事务id提交该事务，请看这里，它是远程服务器还是本地服务器？您是否尝试重新启动PostgreSQL server？它是一台本地服务器，我尝试重新启动PostgreSQL server，但没有结果。我遇到了类似的问题-这是由于尝试在我的应用程序中智能使用init.py造成的。在那里，我导入了我的表单和测试（以便runserver和django autotest能够获取它们）。通过将它们包装在一个if块中，该块检查了argv中我想要的服务器命令，它得到了修复。感谢您确认此问题。嗨，Praveen，您是否有一些关于Postgresql中事务的指针？如何查找打开的事务、提交或回滚它们？
