flink pg cdc 在同步数据库的时候一直会报检查点失败，我看了哈每次都是同样的两个数据库。

我想问一下，pg cdc 在执行检查点的时候是不是要和数据库有关系，比如提交slot 的消费点，我手动改了一下这两个数据库中监控的表，检查点马上就成功了，还有就是检查点执行频繁了对数据库性能有影响没得，如果这个库长时间没有变动，会导致检查点失败，有什么解决办法没得(目前我想到就是定时更新一个表中的某条数据)。下面是我改了数据后的检查点，基本上都是成功。

flink cdc数据库历史主题或其内容完全或部分丢失。请检查数据库历史主题配置，然后重新执行快照？

Flink CDC换了一台数据库检查点就疯狂失败，在执行检查点的时候与数据库有关系没得？

Flink CDC换了一台数据库检查点就疯狂失败，前面几次还是好的，后面就失败了，pg cdc 同步，flink 在执行检查点的时候与数据库有关系没得？
