How to Install PostgreSQL 9.3 on Oracle Linux
For whom are not familiar with PostgreSQL, it is an open source object-relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness. Like all other enterprise companies, we use different databases beside Oracle to lower the costs. We prefer PostgreSQL instead of Microsoft SQL Server, because it supports PL/SQL for some degree.
In this blog post, I’ll try to show how to install PostgreSQL using YUM. YUM (Yellowdog Updater, Modified) is an open-source command-line package-management utility for Linux operating systems using the RPM Package Manager. It handles library dependencies, so it’s the easiest and maybe the best way to install any RPMs. In this blog post, I’ll install PostgreSQL on Oracle Linux because I use Oracle Linux when I need a Linux OS, and its support costs are lower than Redhat Enterprise Linux. In next weeks, I’m also gonna blog about backup and replication for PostgreSQL, and maybe (not promising) blog about some key concepts of PostgreSQL such as MVCC, vacuum and vacuum freeze.
I assume that you can install Redhat or Oracle Linux. You may read my old post about installing Oracle Linux, hopefully it would be useful. Anyway, if our Linux server is ready, we can download and install Repository RPM for our server. Visit http://yum.postgresql.org.
