PostgreSQL is a fully featured object-relational database management system. It supports a large part of the SQL standard and is designed to be extensible by users in many aspects. Some of the features are: ACID transactions, foreign keys, views, sequences, subqueries, triggers, user-defined types and functions, outer joins, multiversion concurrency control. Graphical user interfaces and bindings

This document tries to describe building of a Debian package to the common Debian user, and prospectus developer. It uses pretty common language, and it's well covered with working examples. There is an old Roman saying, Longum iter est per preaecepta, breve et efficax per exempla! (It's a long way by the rules, but short and efficient with examples!).

Learn the basics of creating Debian packages for distributing programs and source code. This article shows all the necessary components of a package and how to put them together to end up with a final product.

If you packaging software for Debian Linux or (K)Ubuntu sometimes you need not only one package, but you have to provide a dependency like a library or whatever. When those dependencies are not in the official repositories, the only way to fulfill those dependencies is to put your package inside the repository.

This document describes the steps to setup a chroot jail for building Ubuntu packages using pbuilder. It is recommended for Ubuntu maintainers or anyone interested in building packages using Ubuntu.

You can build packages without pbuilder but you must already have all the build dependencies of the package that you are building installed on your running system.

The following assume you want to install breezy.

There are always a few packages that you want to install that don't exist in the Ubuntu repositories. If they have any dependencies on other packages, trying to using dpkg can drop you into "dpkg hell", and having apt resolve those dependencies for you would really help. There are full blown methods of creating your own repository, such as Debarchiver or Dak.

This document explains what a Debian repository is and how you can set up one.

So, what do you do if the program already exists as a Debian package (official or non-official) and you just need to tweak or customize it? You don't want to go to the trouble of downloading the upstream source and creating a whole new package. Or what if you want to backport a package from Sid to Sarge? Your best option is to download the source package and customize it yourself.

This HOWTO was inspired by several things:

• A desire to more effectively manage some packages I have backported and created locally (kernel images and JDK packages).
• A desire to help others who are interested in creating a local repository.
• A desire to help extend some of the available documentation, which does not go into sufficient detail.
• An inte
