Thanks for the reply.
I was hoping to avoid using C. Am I correct about
my assumption that having, say, 30 IF..END IF blocks
in one trigger is more efficient (in terms of
execution speed and server load) than 5 update
triggers per table?
I'm just wondering if it's worth the effort to do it
in C or just use lots of plpgsql triggers.
