Overview of this book

PostgreSQL is the most advanced open source database in the world. It is easy to install, configure, and maintain by following the documentation; however, it’s difficult to develop applications using programming languages and design databases accordingly. This book is what you need to get the most out of PostgreSQL You will begin with advanced SQL topics such as views, materialized views, and cursors, and learn about performing data type conversions. You will then perform trigger operations and use trigger functions in PostgreSQL. Next we walk through data modeling, normalization concepts, and the effect of transactions and locking on the database. The next half of the book covers the types of indexes, constrains, and the concepts of table partitioning, as well as the different mechanisms and approaches available to write efficient queries or code. Later, we explore PostgreSQL Extensions and Large Object Support in PostgreSQL. Finally, you will perform database operations in PostgreSQL using PHP and Java. By the end of this book, you will have mastered all the aspects of PostgreSQL development. You will be able to build efficient enterprise-grade applications with PostgreSQL by making use of these concepts

Preface

Summary


In this chapter, we covered how to create, compile, and install extensions. Every extension has its own usage, so simply creating extensions that you do not use does not hurt much; however, it unnecessarily increases the count of objects in the database. As PostgreSQL is the most popular open source database, there are plenty of contrib and external extensions that are available in the market openly. Additionally, we also covered db links, which is useful when you are working with multiple databases. There are many applications that store large objects in the database, so we took a look at those as well. In the next chapter, we will cover how to connect Postgre with PHP, and how to deal with DDLs, DMLs, and SELECT with PHP. We will describe this with practical examples that will help you test yourself locally before implementing your actual requirements.
