我可以看到有人建议使用 postgresql 驱动程序，而不是 redshift 驱动程序。

但是当我尝试使用 postgresql 驱动程序时，我得到的错误是：

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

请建议我应该在哪里进行更正？

【参考方案1】：

事实上没有为 postgresql:/redshiftHost:5439/trivusdev 找到合适的驱动程序 你确定这是正确的 URL，URL 应该如下所示：

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

我认为您在主持人之前错过了jdbc:.. 和/。

您可以在这里了解更多信息：Creating a custom Database connection

希望对你有帮助。

这就是缺少的东西，它现在可以创建连接了。
