This manual is part of the official reference documentation for PostgreSQL 9.0. It describes all the SQL commands available in PostgreSQL. There are over 140 commands from ABORT to VALUES each with a full usage synopsis, description, annotated parameter list and examples. Important commands such as SELECT and GRANT receive extended coverage. The associated client and server command-line tools like psql, pg_dump and pg_restore are also documented. This volume is part of a set. The separate Volume 1A "The SQL Language" (ISBN 978-1-9[zasłonięte]06966-1) documents the SQL language syntax, functions and datatypes as implemented by PostgreSQL. Volumes 1A and 1B are intended to be used together. The further additional volumes of this series are Volume 2, the "Programming Guide" (ISBN 978-1-9[zasłonięte]06966-5), and Volume 3, the "Server Administration Guide" (ISBN 978-1-9[zasłonięte]06966-2). For each copy of this manual sold 1 USD is donated to the PostgreSQL project by the publisher, Network Theory Ltd.
