Description:        pgsql NEW dinamic columns change
Details:

Hi. I want to make a trigger for more tables that then i try to make a
update to make a new insert. i find a solution in next syntax
INSERT INTO TG_RELNAME SELECT NEW.*;
RETURN OLD;

the problem is that the primary key is violated because NEW.id_client
already exists.

i try to find a solution for change

NEW.<variable>=new_sequence .I can make this but the problem is how to
concatenate NEW with the variable???
I have solutions for put in the char or text <variable> the corect primary
key.


Please send me a solution or make a update at pgsql because a lot of people
need to change dynamic NEW or OLD columns(see in google : dynamic access
RECORD  columns)

thanks...
PS: when it will be finsih slony2 syncronus master-master. I use very well
until now master with 10 slaves via VPN,but i will need master-master
solution for free.
