[TRIGGER] Returning values from BEFORE UPDATE trigger, without using them

Hello,

i have a non-trival problem and i do not believe that it is solvable.

I have defined an BEFORE UPDATE trigger. The trigger catch every update, 
change some columns of the new row, make an insert of the new row and 
returns null to abort the update.
All fine till here :)

Now the problem: if i do an UPDATE table [..] RETURNING * it returns 
always null. This is correct behavior, because the UPDATE is canceld by 
the trigger which returns null, so the updated data is "null".
But i want to get the new data inserted by the trigger without a new 
select. Is there a possibility to get the inserted data or do i have to 
do a select after the update?

Greetings,
Torsten
