我在做單元測試（使用NUnit）PostgreSQL的，不幸的是它會導致一個錯誤：什麼原因導致：Unix傳輸錯誤？
Internal error
RemotingException: Unix transport error.
注：如果我使用SQLite的錯誤不會發生

什麼可能是我單元測試Postgresql時可能的原因，結果爲RemotingException：Unix傳輸錯誤。？
如果我在單元測試（例如Main）之外運行代碼，它可以工作。順便說一句，如果我的單元測試SQLite的，它不會引起找到答案的任何錯誤太
聽起來像你的程序試圖通過套接字而不是端口連接。你能配置連接器使用Postgres TCP/IP端口嗎？ – 2010-12-03 10:10:02
