Who this book is for

This book is intended for developers and database administrators who already know a few of the basic concepts about relational databases, SQL statements, and transactions. Because the installation and configuration of PostgreSQL is out of the scope of this book, readers should already be familiar with how to run and interact with PostgreSQL.

In this book, we are going to learn about the main features that PostgreSQL provides in order to ease the development of code on the database side, as well as how to use code to implement business rules and keep data under control and consistent. As it is focused on the development side, this book does not cover other topics related to the database, such as tuning, query optimization, privileges, or replication.
