PostgreSQL leads the reader through the internals of the powerful PostgreSQL open source database. Throughout the book, readers will find explanations of data structures and algorithms, each backed by a concrete example from the actual source code. Each section contains information about performance implications, debugging techniques, and pointers to more information (on Web and in book form). The reader will find an easy to read, code-based approach that makes it easy to understand how each feature is implemented, how to best use each feature, and how to squeeze more performance from database applications.

Korry Douglas is the Director of Research and Development for Appx Software. Over the last two decades, he has worked on the design and implementation of a number of high-level, high-productivity languages and development environments. His products interface with many relational (and non-relational) databases. Working with so many different database products (Oracle, Sybase, SQL Server, DB2, PostgreSQL, MySQL, MSQL) has given him a broad understanding of the commonalities of, and differences between, databases.
Susan Douglas is the President and CEO of Conjectrix, Inc., a software company specializing in database technologies and security tools. Consulting to the end-user community has given her widespread database experience and a real appreciation for high-quality programs and flexible tools powerful enough to handle data well and intuitive enough to actually use.
Korry and his wife (and best friend) Susan raise horses in rural Virginia. Both are natives of the Pacific Northwest, but prefer the sunshine and open spaces offered by Virginia. They both telecommute, preferring to spend as much time as possible with their 200 or so animal friends (who never complain about buggy code, inelegant design, or poor performance). Susan is an avid equestrienne; Korry gets to clean the barn.
