Point In Time Recovery (PITR) backup techniques allow you to restore to a specified point in time, so you could restore up to the point immediately before the problem transactions. > I would assume yes but I wanted to > check if there was some type of timestamp that would prevent an issue > from occurring? Take another look at this section -- in particular, recovery_target_time. I hope this helps. -Kevin
