Overview of this book

This second edition of Mastering PostgreSQL 11 helps you build dynamic database solutions for enterprise applications using the latest release of PostgreSQL, which enables database analysts to design both the physical and technical aspects of the system architecture with ease. This book begins with an introduction to the newly released features in PostgreSQL 11 to help you build efficient and fault-tolerant PostgreSQL applications. You’ll examine all of the advanced aspects of PostgreSQL in detail, including logical replication, database clusters, performance tuning, monitoring, and user management. You will also work with the PostgreSQL optimizer, configuring PostgreSQL for high speed, and see how to move from Oracle to PostgreSQL. As you progress through the chapters, you will cover transactions, locking, indexes, and optimizing queries to improve performance. Additionally, you’ll learn to manage network security and explore backups and replications, while understanding the useful extensions of PostgreSQL so that you can optimize the speed and performance of large databases. By the end of this book, you will be able to use your database to its utmost capacity by implementing advanced administrative tasks with ease.

PostgreSQL Overview

Summary

In this chapter, you learned about the advanced features provided by SQL. On top of simple aggregates, PostgreSQL provides ordered sets, grouping sets, windowing functions, and recursions, as well as an interface that you can use to create custom aggregates. The advantage of running aggregations in the database is that code is easy to write, and a database engine will usually have an edge when it comes to efficiency.

In Chapter 5, Log Files and System Statistics, we will turn our attention to more administrative tasks, such as handling log files, understanding system statistics, and implementing monitoring.
