In our previous article we saw three classic Database Modelization Anti-Patterns. The article also contains a reference to a Primary Key section of my book The Art of PostgresQL, so it’s only fair that I would now publish said Primary Key section!

So in this article, we dive into Primary Keys as being a cornerstone of database normalization. It’s so important to get Primary Keys right that you would think everybody knows how to do it, and yet, most of the primary key constraints I’ve seen used in database design are actually not primary keys at all.
