What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

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.

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.

Tiene base teórica, ejemplos prácticos, bastante completo en sus explicaciones, además de que referencia a documentos en internet (las URLs han cambiado desde la edición del libro y es el único fallo que le encuentro).
