In Detail
PostgreSQL is a powerful, open source, object-relational database system. PostgreSQL offers many advantages for your company or business over other database systems.
This book is your practical guide to understanding the advanced techniques used to handle complex data and methods to solve issues that you might face while working with PostgreSQL. We will start with discussing the issues that arise at the time of setting up PostgreSQL. The next step will be to decide which data types will be most suitable to the task at hand and optimize performance using the right ones.
We will understand how to deal with transaction locks, fuzzy matches, cursors, joins, and so on. Know the warning signs to look for, and how to avoid the most common issues before they even happen. In addition to that, specific high-level topics such as replication and Point-In-Time-Recovery will be discussed. The entire book is based on PostgreSQL 9.4 and contains up-to-date information.

0 of 0 people found the following review helpful. Pretty useful read By tony I felt like I learned quite a bit by reading this book. As someone who works on an ops team that uses PostgreSQL as part of our stack, there were a few things that I found fairly helpful such as the queries related to finding out how Postgres determines the best method of execution and how the order of a query is executed. The query order outline was very helpful. Additionally, this book highlights some useful functionality that is already contained in PostgreSQL, such as the distance operator for geometric values, that save time by including it as a query instead of having to write a specific function.In terms of its organization, it seems to touch on all of the most common pain points such as indices, normalization (although it doesn't touch too much on the concept except to explain how this can get out of hand), replication, joins, etc. I'll continue to use this book as a reference, especially when going through the PostgreSQL documentation to research a problem finds daunting (although I'm usually able to find what I'm looking for with a simple search).I would note that this book is, like PostgreSQL in general, much more for Linux, a little less for OSX and a lot less for Windows. Some sections, such as modifying the OS parameters (primarily kernels) for optimization require some background knowledge as the different kernel parameters are not explained so much as they are presented as "change your kernel parameter to this". Other concepts, such as checksums, are recommended but not necessarily explained very much (although a Google search or browse on Wikipedia should clear that up if you're not familiar).I don't think this book is so much for someone who's working with PostgreSQL for the very first time, but intermediate users should not have any issues following along and picking up tips to optimize their performance. The explanations on data type comparisons were pretty good as well.
1 of 1 people found the following review helpful. PostgresQL Pro-Tips By Unix Lists No one can argue: the Official PostgreSQL Documentation is solid, comprehensive, and very-well organized. It is also, however, extremely massive and as a result can be difficult for newcomers and even non-newcomers to navigate at times, especially in a pinch.On the subject of troubleshooting, this book covers the core items you need to know in order to run Postgres effectively. The section on Monitoring in particular, is invaluable, and topics such as Indexing, Transactions, Backups, and Replication are also covered.The book is a joy to read. It is written in a casual, yet practical manner and while not a large text, is nonetheless packed with practical tips and is a perfect guidebook for Troubleshooting.
