Hi,
I am using pg 7.4.1 and have created a trigger over table with 3 M rows.
If I start masive update on this table, pg executes this trigger on
every row and dramaticaly slows the system.
Exists in pg any way to define the trigger execution only if I have
changes on some fields?
For example I am able to declare this in oracle.
My trigger is writen in pgSQL.
regards,
ivan.
