Phenomenal book, gets right to the point and reads quickly and conversationally. We had some issues with performance with ingesting large data sets and I was able to read this book in an afternoon and figure out where we needed to go in order to speed things up. There's a ton of just really great info in this book and pretty much no beginner info, other than clarifications where the official documentation might be ambiguous.The only missing thing in the indexing chapter is a discussion about full text indexing (which does a really great job of performing better than the pg_trgm extension suggested in that chapter for our particular use case - wildcard matching with unanchored LIKE predicates).

Excellent guide on troubleshooting PostgreSQL--offers a few good tips not covered as thoroughly in my other PostgreSQL books. Very handy reference with with examples and illustrations.

Libro che offre spunti davvero molto interessanti per configurare postgres e strutturare/gestire al meglio i propri database. Utile anche da affiancare alla documentazione ufficiali.

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.

I work with PostgreSQL since version 7.3, I don't claim to be an expert, but I believe I know enough concepts about such system. The book is interesting, but it just points out to possible problems the author had faced during his life. I was expecting something more complex and deeper, like an index checklist or hardware sizing.
