Hello there,

I am a total novice to Postgresql, but very much interested in learning how
it works.

I have to modify the source code of Postgresql-9.0.1 such that whenever I
run an UPDATE command it should print out the old and new tuples. Since I am
a beginner I would appreciate it a lot if anyone of you out there could
point me in right direction. Which files will I need to modify to get the
desired results?
