PostgreSQL is perhaps the most robust and capable of all the open source databases. Authors John C. Worsley and Joshua D. Drake provide this practical guide to using PostgreSQL based on their many years of experience providing PostgreSQL-based solutions to their clients.Early chapters of Practical PostgreSQL introduce PostgreSQL and take you quickly through the process of obtaining the PostgreSQL software and installing it on your system. Youll learn about psql, the PostgreSQL command-line interface, and all the basic SQL features PostgreSQL supports.
