我能够看到有人建议使用postgresql驱动程序，而不是使用redshift驱动程序。
但是当我尝试使用postgresql驱动程序时，我得到错误：
No suitable driver found for postgresql://.....
请建议我应该在哪里进行更正？
答案 0 :(得分：2)
实际上没有为postgresql找到合适的驱动程序：/ redshiftHost：5439 / trivusdev 你确定这是URL应该是这样的正确URL：
jdbc:postgresql://redshiftHost:5439/trivusdev?OpenSourceSubProtocolOverride=true
我认为您错过了主持人之前的jdbc:..和/。
您可以在此处了解详情：Creating a custom Database connection
希望这可以帮到你。
