Worsley John, Drake Joshua. Practical PostgreSQL: A Hardened, Robust, Open Source Database

O’Reilly Media, 2002. — 638 p. — ISBN: 1-56592-846-6.Arguably the most capable of all the open-source databases, PostgreSQL is an object-relational database management system first developed in 1977 by the University of California at Berkeley. Despite its long history, this robust database suffers from a lack of easy-to-use documentation. Practical PostgreSQL fills that void with a fast-paced guide to installation, configuration, and usage.
