There is an article on normalisation at IBM developer works for all
those who need a primer on table normalisation.
I learnt this from, would you believe, "dBase Mac" by Jim Heid when I
was one of the two users in the world running that version in 1988-1989
=:-D
I recomend "Database Application Programming with Linux" Wiley. There
are some good table design chapters even for non Linux people.
Good database design helps make PostgreSQL run fast.
