I use a templating engine (Cheetah, http://www.cheetahtemplate.org/
but you are free to use cpp, m4, anything) to manage my SQL files, so
it is quite easy to create N triggers, no matter how large N is.
I do not know a pure PostgreSQL solution. Remember that the problem is
not obvious to solve in a general way. For instance, there are
typically fields for which you do not regard a SQL update as a "real"
(worthy of recording) update.
