我对PostgreSQL的这个恼人的消息感到困惑。我可以通过ODBC正确连接到服务器，但是任何尝试运行公共选择查询都会产生一条消息＆＃34;无效的对象名称＆＃39; some_view＆＃39;＆＃34; （其中“some_view＆＃39;是我应该能够读取数据的视图”）。有趣的是，这个查询在通过pgAdmin执行时工作正常。
[编辑]
该项目在MFC。我使用CRecordset。已经尝试使用选项CRecordset::executeDirect和CRecordset::noDirtyFieldCheck，但没有成功。
似乎问题是由MFC和/或CRecordset类引起的。当我尝试使用与.NET应用程序相同的DSN连接并执行相同的查询时，一切正常。
[EDIT2] 我粘贴了Postgres日志的内容：
