postgreSQL12

Question

pg12，服务启动正常，日志一直报：

把端口号当成role了？还没有办法创建5432这个role，以下是配置信息：

引用GPT回答：
在组合起来进行仿真时，可能存在一些时序和同步问题导致输出不正确。具体可能原因有很多，需要进行详细的分析和调试。

首先，你可以检查频率测量模块的输出是否按预期工作。如果该模块的输出正确，则问题可能出在频率分频模块中。

其次，你可以检查频率分频模块的时序和同步是否正确。例如，你可以检查时钟边沿是否正确、信号延迟是否正确等等。

最后，你可以使用模拟器进行调试，以确定是否存在其他问题。可以通过波形查看器来检查各个信号的变化情况，从而找出问题所在。

总之，需要仔细分析和调试，逐步确定问题所在，才能解决频率分频模块输出不正确的问题。
