You mean a table, don't you?

You want the displayed page to refresh each time the user selects a different row? What if the the user does not change rows, but the selected row changes whilst she's looking at it?

Up-to-the-second aggregate stats are costly. You will have to decide how much out-of-dateness can be tolerated---one sec, 10 secs, one minute, &c---then write a refresh procedure which runs that often. A last_update_time column can make such a procedure less costly.
