Beginner - Advanced Level Users.
PostgreSQL is the most robust, object-relational database management system of all the open source database options. It has been open source from the start, and evolves quickly, thanks to the committed, active community of developers behind it. But like many open source applications, it lacks comprehensive, easy-to-use documentation.
This book fills the information void. It is a fast-paced, business-oriented guide to installing, configuring and running PostgreSQL. Readers will find all the basics here, such as how to create databases and objects, such as tables, within those databases. Or they can go straight to advanced topics like inheritance, replication, user management and backup and recovery.
The book also introduces the PL/pgSQL procedural language. Finally, a complete PostgreSQL command reference makes 'looking it up' easy.
