Overview of this book

PostgreSQL is one of the most powerful and easy to use database management systems. It has strong support from the community and is being actively developed with a new release every year. PostgreSQL supports the most advanced features included in SQL standards. It also provides NoSQL capabilities and very rich data types and extensions. All of this makes PostgreSQL a very attractive solution in software systems. If you run a database, you want it to perform well and you want to be able to secure it. As the world’s most advanced open source database, PostgreSQL has unique built-in ways to achieve these goals. This book will show you a multitude of ways to enhance your database’s performance and give you insights into measuring and optimizing a PostgreSQL database to achieve better performance. This book is your one-stop guide to elevate your PostgreSQL knowledge to the next level. First, you’ll get familiarized with essential developer/administrator concepts such as load balancing, connection pooling, and distributing connections to multiple nodes. Next, you will explore memory optimization techniques before exploring the security controls offered by PostgreSQL. Then, you will move on to the essential database/server monitoring and replication strategies with PostgreSQL. Finally, you will learn about query processing algorithms.

Replication using Bucardo


In this recipe, we are going to show the replication between two databases using Bucardo, which is another replication tool that replicates data among multiple master nodes. As with the other two tools, this tool is also dependent on triggers at the source tables.

Getting ready

This exercise is carried out in a Red Hat Linux machine.

Install the EPEL package for your Red Hat platform from the following URL:  https://fedoraproject.org/wiki/EPEL.

Then install these RPMs with the following yum command:

yum install perl-DBI perl-DBD-Pg perl-DBIx-Safe 

If it is not already installed, download the Postgresql repository from the following web link:  http://yum.pgrpms.org/repopackages.php

After this, install the following package. This is required because Bucardo is written in Perl:

yum install postgresql96-plperl

To install Bucardo, download it from the following web link: http://bucardo.org/wiki/Bucardo

Extract the tarball and go to the newly downloaded location and...
