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.

Toward PostgreSQL 13

In this final chapter of the book, you will discover the new features that the upcoming PostgreSQL 13 release is going to introduce. You will also learn what the main differences between PostgreSQL 13 and the previous stable 12 version are and how to prepare for a version upgrade. Presenting every new feature in detail is out of the scope of the chapter, and a few changes have been already introduced in the previous chapters and will be reviewed here.

The new features have been organized into categories as follows:

  • Replication
  • Administration of the cluster
  • The command-line interface (psql)
  • Performance
  • Backup and related tools

As you can imagine, not every feature fits into a single category, and not every category can summarize the new features, but what's presented in this chapter should help you get a clear idea of what is new in PostgreSQL 13.
