Postgres异常：javax.transaction.HeuristicMixedException：启发式异常

Question

我正在Windows上使用Spring和PostgreSQL 9.2创建一个应用程序。我成功地在Windows 32位操作系统中运行此应用程序。但是当我尝试在Windows 64位操作系统中运行时，同样的应用程序，我得到以下异常：

....为什么我会遇到这个问题？

Answer 1

结合PostgreSQL 9.x和10.x，这个问题与Seam和Apache JCR一起经历，并且在PostgreSQL配置中max_connection和max_prepared_transactions的值太低。
