PostgreSQL Essential Reference is designed for anyone who plans to use PostgreSQL or the new RedHat DB. It is also a valuable source of information for web developers, administrators, and programmers. This book is packed with clear and concise information on everything from basic SQL commands and common administrative tasks to programming applications and using PostgreSQL APIs. A noteworthy accomplishment of this book is the layout-all the subjects are clearly presented, and the reference style makes looking up information quick and easy. Each topic is arranged both by task and alphabetically, and includes important information such as feature notes, syntax, and example code. Barry Stinson has written this detailed reference book with the explicit intent to make this the only book you need.
