【 TiDB 使用环境】生产环境
【 TiDB 版本】5.3.1
【复现路径】 alter table x.y set tiflash replica 1;
【遇到的问题：问题现象及影响】
问题：添加tiflash副本导致tiflash节点报错
现象：无法添加tiflash副本，报错： Detected overflow when decoding data 18446744073709551615 of column ipnum with type Nullable(UInt32)
该表为按天range的分区表，报错日志中的对应字段的定义：ipnum int(10) unsigned DEFAULT NULL
