  • Improve reliability, fault-tolerance, and accessibility by maintaining consistency between redundant resources
  • Get grips with the latest version of PostgreSQL with this example-based guide
Who This Book Is For

This book is ideal for PostgreSQL administrators who want to set up and understand replication. By the end of the book, you will be able to make your databases more robust and secure by getting to grips with PostgreSQL replication.

What You Will Learn
  • Use Point-in-time Recovery to perform data recovery as well as replication
  • Set up synchronous as well as asynchronous streaming replication
  • Get familiarized with the transaction log, the core component of most replication setups and its purpose
  • Improve speed and reliability with an understanding of pgpool and PgBouncer
  • Increase your data security and geographically distribute data
  • Make your systems more available and secure with Linux High Availability
  • Scale out with PL/Proxy and Postgres-XC
  • Detect, investigate, and solve replication-related problems
In Detail

PostgreSQL offers a comprehensive set of replication related features. Unleashing the power of PostgreSQL provides you with countless opportunities and a competitive advantage over other database systems.

This book will guide you through the most important concepts of PostgreSQL replication. It contains all the information you need to design and operate replicated setups.

Beginning by giving you an understanding of replication concepts, the PostgreSQL transaction log, and Point-in-time Recovery, we gradually move on to setting up asynchronous and synchronous replication. Next up, you will learn to monitor a PostgreSQL cluster setup, deal with monitoring tools, and then move on to understanding Linux High Availability. Further, we explore widely-used tools such as Slony, SkyTools, Postgres-XC, and walbouncer, and set up PL/Proxy.

Nice coverage of the available replication methods
By Jeff L
This book is a great introductory text to anyone needing to get started with data replication on PostgreSQL and is unsure about how to get started. It covers all of the major replication technologies currently available and describes some of the benefits and limitations of each. General optimization strategies to improve replication performance are also covered. Since the scope of coverage is pretty wide across all of the different replication technologies, this book doesn't quiet have enough space to devote more than single chapter to each, so you may still need to consult other manuals and reference materials once you've narrowed down your replication strategy.

Phenomenal walkthrough of configuring replication & point-in-time-recovery on PostgreSQL 9.4
By Lance Alligood
Normally when I am googling for assistance with PostgreSQL, it's all but guaranteed that at least one of the first 3 hits is for the postgresql.org. However, when it came to configuring master-slave replication, that wasn't the case. Most of the hits were instead for various blog posts or forums. Any details were frequently poorly formatted, glossed over--or omitted(!)--important steps, and never supplied adequate background information for the values assigned to parameters in postgresql.conf. To make matters worse, there was little mention of what version of PostgreSQL the instructions were for in those posts. My frustration level was off the charts as I tried to make sense of this poor & inconsistent "documentation"!

I was in (desperate!) need of some accurate, explanatory guidance to get replication & point-in-time-recovery (PITR) up & going on my PostgreSQL 9.4 servers. Normally the PostgreSQL project is fantastic in supplying clear & precise documentation for commands & components of the database, but that just isn't the case at all when it came to making sense of replication and/or PITR. However, I must fully acknowledge that the PostgreSQL project has been exerting considerable effort into improving the ease of configuration & use when it comes to replication & PITR. (And it's only a matter of time the website documentation is there to go along with it.) Based on my searches, there have been massive changes in replication & PITR for (at least) 9.1, 9.2, & 9.3.

PostgreSQL Replication Second Edition just came out in July 2015 so it is thankfully relevant to 9.4, although the changes from 9.3 -> 9.4 (command-wise at least) appear to be less dramatic than the previous 9.x releases. This was very much the documentation I was looking for! I have no issues with an author nor a publisher putting out a well-written book, but why PostgreSQL doesn't have webpages on its site comparable to this excellent tome is a real head-scratcher. That said, this book definitely lives up to the hype of showing you what it takes to get either/both replication or PITR running on PostgreSQL. I was particularly thankful for the explanation of the main files/directories that make up the database & all of the necessary parameters in postgresql.conf & pg_hba.conf!

The project admits that there will certainly be more changes in the future--and I'm quite certain they'll all be for the better!--when it comes to replication & PITR, but for the hear & now in late 2015, this book will get you up to speed on configuring those with the current tools right now, quickly, & with little effort.
