Learn PostgreSQL

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.

Introducing PostgreSQL 13's new features

In every release, the PostgreSQL Global Development Group introduces a set of new features that span from performance improvements to configuration management to adherence to the SQL standard and so on. PostgreSQL 13 follows its own path and introduces a rich set of new features; many of them are "under the hood" and so you will not perceive them during day-to-day database usage, but they are really important for the cluster to work more efficiently.

This section provides you with a categorization of the main features introduced with the upcoming PostgreSQL 13 release, which at the time of writing is still in beta 2 release, so it's stable enough for usage and testing but not yet production-ready. As you can imagine, it is not possible to explain (or even worth explaining) every single feature in detail, so you will just get an at-a-glance idea of the main changes. The changes are presented in no particular order.
