+
+ <para>
+ This book is for PostgreSQL application programmers. It is divided into three parts.
+ </para>
+
+ <para>
+ The first part of this book describes the client programming
+ interfaces distributed with PostgreSQL. Each of these chapters
+ can be read independently. Note that there are many other
+ programming interfaces for client programs that are distributed
+ separately and contain their own documentation. Readers of the
+ first part should be familiar with using SQL commands to
+ manipulate and query the database (see the &cite-user;) and of
+ course with the programming language that the interface uses.
+ </para>
+
+ <para>
+ The second part of this book is about extending the server
+ functionality with user-defined functions, data types, triggers,
+ etc. These are advanced topics which should probably be
+ approached only after all the other user documentation about
+ PostgreSQL has been understood.
+ </para>
+
+ <para>
+ The third part of this book described the available server-side
+ programming languages. This information is related to the second
+ part and is only useful to readers that have read at least the
+ first few chapters thereof.
+ </para>
+
+ <para>
+ This book covers <productname>PostgreSQL &version;</productname>
+ only. For information on other versions, please read the
+ documentation that accompanies that release.
