比如我执行
cat /data/file4g &> /dev/null
进程退出后，page cache是有缓存这个文件的。但是pgcacher -top -limit 5 无法扫描出

I probably know what the problem is. pgcacher scans the collection of files opened by the process. If the file is closed by the process, it cannot be traced. Because pgcacher cannot know which files he has opened.
