In this document, the internals of PostgreSQL for database administrators and system developers are described.

PostgreSQL is an open source multi-purpose relational database system which is widely used throughout the world. It is one huge system with the integrated subsystems, each of which has a particular complex feature and works with each other cooperatively. Although understanding of the internal mechanism is crucial for both administration and integration using PostgreSQL, its hugeness and complexity prevent it. The main purposes of this document are to explain how each subsystem works, and to provide the whole picture of PostgreSQL.

This document is based on the second part of the book I wrote in Japanese in 2012 (ISBN-13: 978-4774153926) which is composed of seven parts, and covers version 11 and earlier.

Author

Hironobu SUZUKI

I graduated from graduate school of information engineering (M.S. in Information Engineering), have worked for several companies as a software developer and technical manager/director. I published seven books in the fields of database and system integration (3 PostgreSQL books and 3 MySQL books).

As a director of the Japan PostgreSQL Users Group (2010-2016), I organized the largest (non-commercial) technical seminar/lecture of PostgreSQL in Japan for more than six years, and also served as the program committee chair of the Japan PostgreSQL Conference in 2013 and as a member in 2008 and 2009.

Cuando era joven, vivió en Sudamérica por unos años. Recientemente, a veces vuelve a allí.

Now I live in Dublin, Ireland, and my next challenge is to be a PostgreSQL developer.
