hello,
I have a somehow related question to this topic: is it possible to know
(in postgresql) if an update on a column is absolute (set col = 3) or
relative to it's previous value (set col = col + 3)
in a trigger one have access to OLD row values and NEW row values, but
no correlation between the two. is this type of information available
somewhere in postgresql ?
thanks,
Razvan Radu

Hi everyone,
I'm focus on temporal databases (not temporary), and I want to know
if anyone here is studying this tecnologies too. So, we can exchange
knowlegment. Specifically, anyone who is trying to implement on
postgresql the aspect of time (temporal).
These researches are lead by Richard Snodgrass. So, anyone who have
something to share, please contact me!
Thanks!!!
