Learn PostgreSQL

By: Luca Ferrari, Enrico Pirozzi

Overview of this book

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 12 and 13 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.

Introduction to PostgreSQL

PostgreSQL is a well-known open-source relational database, and its motto states what the project intends to be: the most advanced open-source database in the world.

The main qualities that attract masses of new users every year and keep current users enthusiastic about their projects are its rock-solid stability, scalability, and safeness, as well as the features that an enterprise-level database management system provides.

But PostgreSQL is not just a database; it has grown to be a whole ecosystem of extensions, tools, and languages tied together by communities spread around the world.

PostgreSQL is an open-source project and is fully developed in the open-source world. That means that there is no single entity in charge of the project and the result is that PostgreSQL is not a commercial product. In other words, PostgreSQL belongs to everyone, and...
