I think that the Undo function of AWS and Oracle's Flashback function are to save such users, and it is a function to prevent human error. So, how about postgres implementing such a function? Also, as an approach to achieving the goal, I thought about outputting lsn to the server log when a specific command was executed. I do not think the source code of postgres will be complicated when implementing this function. Do you feel it is too complicated? ------- Naoki Yotsunaga
