Обсуждение: absolute or relative updates
I want to write a trigger that logs any changes that are made to a row. I have the old an new row values, but I am more interested in knowing if the update was absolute "UPDATE table SET col = 3" or relative "UPDATE table SET col = col + 2". Is the a way (any way) to access this type of information ? In any language available (C, PLPGSQL, etc.) Thanks Razvan Radu

If you want restore a table and you have only relative log-entrys, the you must restore all steps from start to this point.
