This is a good comprehensive book for someone coming back to PostgreSQL after not using it for a while.

I'm new to Postgres. My back ground is MS SQL Server. This book helped me greatly, to quickly learn and practice Postgres from the beginning. This book has plenty of examples which you can run yourself and see its execution. So I'd highly recommend this book for anyone who wants to learn Postgres.

G. Wideman Feb 11, 2020

This is not an intro book about PostgreSQL or databases in general, but it is a very good book for someone already generally familiar with databases such as MySQL or SQL Server, who can use some in-depth discussion of the PostgreSQL particulars of a spectrum of essential and moderately advanced topics. Inexplicably, Packt has failed to include the Table of Contents in the Amazon preview, so here it is: 1 Basic Overview 2 PostgreSQL 12 Overview 3 Understanding Transactions and Locking 4 Section 2: Advanced Concepts 5 Making Use of Indexes 6 Handling Advanced SQL 7 Log Files and System Statistics 8 Optimizing Queries for Good Performance 9 Writing Stored Procedures 10 Managing PostgreSQL Security 11 Handling Backup and Recovery 12 Making Sense of Backups and Replication 13 Deciding on Useful Extensions 14 Troubleshooting PostgreSQL 15 Migrating to PostgreSQL 16 Assessment 17 Other Books You May EnjoyIn the past I've found some Packt books utterly abysmal, from incomprehensible writing that was seemingly raw from Google translate, to technical information that was badly organized, irrelevant or just plain wrong. This book is very far from that. The narrative is very readable, the topics are covered at a good level of detail, and often anticipate issues that might puzzle you, or tie in related topics that you would likely want to know. "Well done!" to author Schonig, and to those at Packt responsible for facilitating a good quality result. (But maybe get that ToC into the "Look Inside"?)

Average book, no details on PostgreSQL architecture. Mostly DBA info. Ok topics but adding insights into how it achieves ACID is important as fundamental knowledge

Amazon Verified review

Cathy Hart May 11, 2020

Based on the chapter headings, these topics are clearly important to mastering Postgres. However, delving into the content, the results are well short of mastering. There is repeated use of the words, "understanding", "digging into", "making use of", "handling" but again, well short of accomplishment.For example, in Chapter 9: Handling Backup and Recovery, there is little or no description of the requirements, setup, and execution of said backup and recovery; the subsequent chapter "Making sense of Backups..." is no better. There is hinting insofar as what the syntax is and what a replay command looks like, but no detail of the structure/process of the WAL, checkpoints, lsn's and other important information needed to master the topic. Case in point, in the 'Running pg_dump' section, the entire content of that is one page, half of which is consumed by an example of the command and a screen capture of the output of the --help text. It does mention that pg_dump locks the table, so that's useful, but I can get that from the official Postgres documentation.At no point did I consider myself mastering the topic after reading the brief discussions - I only realized I would have to find another source for more information. I gave it 2 stars becuase the author made good examples and determined a decent outline for the topics. However, if the intent is to produce masters after reading, the book will need to be significantly deeper.
