The PostgreSQL Extension Network (PGXN) is a collection of extensions and tools to manage them in order to ease your experience with extensions. It is very similar to the Comprehensive Perl Archive Network (CPAN). Thanks to the PGXN, developers can share and distribute their extensions to other people, who, in turn, can download and install their extensions.

PostgreSQL is a rock-solid, scalable, and safe enterprise-level relational database. With a broad range of features and stability, it is ever increasing in popularity.This book shows you how to take advantage of PostgreSQL 11 features for server-side programming. Server-side programming enables strong data encapsulation and coherence.
The book begins with the importance of server-side programming and explains the risks of leaving all the checks outside the database. To build your capabilities further, you will learn how to write stored procedures, both functions and the new PostgreSQL 11 procedures, and create triggers to perform encapsulation and maintain data consistency.
