我能看到有人建议使用postgresql驱动程序，而不是红移驱动程序

但当我尝试使用postgresql驱动程序时，得到的错误如下：

No suitable driver found for postgresql://.....

请建议我在哪里进行更正？

事实上没有找到适合postgresql的驱动程序：/redshiftHost:5439/trivusdev您确定这是正确的URL吗URL应该如下所示：

jdbc:postgresql://redshiftHost:5439/trivusdev?OpenSourceSubProtocolOverride=true 

我想你错过了主机前面的一个

jdbc:..

和

/

您可以在此处了解更多信息：

希望这能对您有所帮助。

这就是我们所缺少的，现在就可以创建对话了。
