I'm sorry, but I still must disagree with this advice as it pertains to beginners. I would rather a beginner "overnormalize" their database tables rather than have them default to an array column type. It's much easier to transition from "overnormalized" db tables to one that uses array columns when appropriate than it is to go the opposite direction.
