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.

Partitioning data

Given default 8 K blocks, PostgreSQL can store up to 32 TB of data inside a single table. If you compile PostgreSQL with 32 K blocks, you can even put up to 128 TB into a single table.

Starting with version 10.0, PostgreSQL offers improved partitioning, which will offer end users significantly easier handling of data partitioning.

In this chapter, the old means of partitioning as well as the new features that are available as of PostgreSQL 11.0 will be covered.
