PostgreSQL“DatabaseError：当前事务被中止”

Question

我安装了OSQA并且我同步了（syncdb和migrate）数据库并重新启动了Apache。 在浏览器中，我得到了HTTP状态 200错误，在项目日志中，我收到了很多错误：

DatabaseError: current transaction is aborted, commands ignored until end of transaction block

我还在 PostgreSQL 的日志中发现了这些错误：

LOG:  statement: SELECT "forum_keyvalue"."id", "forum_keyvalue"."key", "forum_keyvalue"."value" FROM "forum_keyvalue" WHERE "forum_keyvalue"."key" = 'FORM_EMPTY_QUESTION_BODY'

我在StackOverflow和I found it上搜索了问题的解决方案：

  

要消除错误，请回滚最后一个（错误的）事务   在修复代码之后：

     

from django.db import transaction transaction.rollback()

此解决方案对我不起作用。
我在Python2.7，Django-1.3.7和PostgreSQL 9.1.11上运行我的应用程序。 任何帮助表示赞赏！非常感谢你，抱歉我的英语不好。
