Welcome to PostgreSQL and the
PostgreSQL Tutorial. The following few
chapters are intended to give a simple introduction to
PostgreSQL, relational database
concepts, and the SQL language to those who are new to any one of
these aspects. We only assume some general knowledge about how to
use computers. No particular Unix or programming experience is
required. This book is mainly intended to give you a hands-on
experience with important aspects of the PostgreSQL system. It
makes no attempt to be a complete or thorough treatment of the
topics it covers.
After you have worked through this tutorial you might want to move
on to reading the PostgreSQL 7.3 User's Guide to gain a more formal knowledge of
the SQL language, or the PostgreSQL 7.3 Programmer's Guide for information about
developing applications for PostgreSQL.
Those who set up and manage their own server should also read the
PostgreSQL 7.3 Administrator's Guide.
