Hello!
I did almost the same by writing a trigger on PL/Ruby that is logging
all table changes + user + other information into the log table in XML
format (the format of the table on which updation/insertion trigger is
fiered is absolutley free and not required to be defind at "compile time").
So you still can view all data changes and build the database but my way
is cappable to view who when changed what, but to build a database
actual at exact moment is difficult enough but still possible.
Best regards,
Anton
