Thinking of migrating to PostgreSQL? This clear, fast-paced introduction helps you understand and use this open-source database system. Not only will you learn about the enterprise-class features in versions 9.5 to 10, but you’ll also discover that PostgreSQL is more than a database system—it’s an impressive application platform as well.
With examples throughout, this book shows you how to achieve tasks that are difficult or impossible in other databases. This third edition covers new features, such as ANSI-SQL constructs found only in proprietary databases until now: foreign data wrapper (FDW) enhancements; new full-text functions and operator syntax introduced in version 9.6; XML constructs new in version 10; query parallelization features introduced in 9.6 and enhanced in 10; built-in logical replication introduced in Version 10.e.
If you’re a current PostgreSQL user, you’ll pick up gems you may have missed before.
- Learn basic administration tasks such as role management, database creation, backup, and restore
- Apply the psql command-line utility and the pgAdmin graphical administration tool
- Explore PostgreSQL tables, constraints, and indexes
- Learn powerful SQL constructs not generally found in other databases
- Use several different languages to write database functions

PostgreSQL is one of the fastest-growing open-source object-relational database management systems (DBMS) in the world. As well as being easy to use, it’s scalable and highly efficient. In this book, you’ll explore PostgreSQL
and learn how to build database solutions using it. Complete with hands-on tutorials, this guide will teach you how to achieve the right database design required for a reliable environment.
You’ll learn how to install and configure a PostgreSQL server and even manage users and connections. The book then progresses to key concepts of relational databases, before taking you through the Data Definition Language (DDL) and commonly used DDL commands. To build on your skills, you’ll understand how to interact with the live cluster, create database objects, and use tools to connect to the live cluster. You’ll then get to grips with creating tables, building indexes, and designing your database schema. Later, you’ll explore the Data Manipulation Language (DML) and server-side programming capabilities of PostgreSQL using PL/pgSQL, before learning how to monitor, test, and troubleshoot your database application to ensure high performance and reliability.
By the end of this book, you’ll be well-versed with the Postgres database and be able to set up your own PostgreSQL instance and use it to build robust solutions.
- Understand how users and connections are managed by running a PostgreSQL instance
- Interact with transaction boundaries using server-side programming
- Identify bottlenecks to maintain your database efficiently
- Create and manage extensions to add new functionalities to your cluster
- Choose the best index type for each situation
- Use online tools to set up a memory configuration that will suit most databases
- Explore how Postgres can be used in multi-instance environments to provide high availability, redundancy, and scalability
This book helps you write queries that perform fast and deliver results on time. You will learn that query optimization is not a dark art practiced by a small, secretive cabal of sorcerers. Any motivated professional can learn to write efficient queries from the get-go and capably optimize existing queries. You will learn to look at the process of writing a query from the database engine’s point of view, and know how to think like the database optimizer.
The book begins with a discussion of what a performant system is and progresses to measuring performance and setting performance goals. It introduces different classes of queries and optimization techniques suitable to each, such as the use of indexes and specific join algorithms. You will learn to read and understand query execution plans along with techniques for influencing those plans for better performance. The book also covers advanced topics such as the use of functions and procedures, dynamic SQL, and generated queries. All of these techniques are then used together to produce performant applications, avoiding the pitfalls of object-relational mappers.
- Identify optimization goals in OLTP and OLAP systems
- Read and understand PostgreSQL execution plans
- Distinguish between short queries and long queries
- Choose the right optimization technique for each query type
- Identify indexes that will improve query performance
- Optimize full table scans
- Avoid the pitfalls of object-relational mapping systems
- Optimize the entire application rather than just database queries
