Welcome to the <productname>PostgreSQL</productname> Tutorial. The
|
|
following few chapters are intended to give a simple introduction
|
|
to <productname>PostgreSQL</productname>, 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 part is mainly intended to give you some hands-on
|
|
experience with important aspects of the
|
|
<productname>PostgreSQL</productname> 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 <xref linkend="sql"> to gain a more formal knowledge
|
|
of the SQL language, or <xref linkend="client-interfaces"> for
|
|
information about developing applications for
|
|
<productname>PostgreSQL</productname>. Those who set up and
|
|
manage their own server should also read <xref linkend="admin">.

<partintro>
|
|
<para>
|
|
This part describes the use of the <acronym>SQL</acronym> language
|
|
in <productname>PostgreSQL</productname>. We start with
|
|
describing the general syntax of <acronym>SQL</acronym>, then
|
|
explain how to create the structures to hold data, how to populate
|
|
the database, and how to query it. The middle part lists the
|
|
available data types and functions for use in
|
|
<acronym>SQL</acronym> data commands. The rest treats several
|
|
aspects that are important for tuning a database for optimal
|
|
performance.

The information in this part is arranged so that a novice user can
|
|
follow it start to end to gain a full understanding of the topics
|
|
without having to refer forward too many times. The chapters are
|
|
intended to be self-contained, so that advanced users can read the
|
|
chapters individually as they choose. The information in this
|
|
part is presented in a narrative fashion in topical units.
|
|
Readers looking for a complete description of a particular command
|
|
should look into <xref linkend="reference">.

|
<para>
|
|
Readers of this part should know how to connect to a
|
|
<productname>PostgreSQL</> database and issue
|
|
<acronym>SQL</acronym> commands. Readers that are unfamiliar with
|
|
these issues are encouraged to read <xref linkend="tutorial">
|
|
first. <acronym>SQL</acronym> commands are typically entered
|
|
using the <productname>PostgreSQL</> interactive terminal
|
|
<application>psql</application>, but other programs that have
|
|
similar functionality can be used as well.

<para>
|
|
This part covers topics that are of interest to a
|
|
<productname>PostgreSQL</> database administrator. This includes
|
|
installation of the software, set up and configuration of the
|
|
server, management of users and databases, and maintenance tasks.
|
|
Anyone who runs a <productname>PostgreSQL</> server, either for
|
|
personal use, but especially in production, should be familiar
|
|
with the topics covered in this part.

The information in this part is arranged approximately in the
|
|
order in which a new user should read it. But the chapters are
|
|
self-contained and can be read individually as desired. The
|
|
information in this part is presented in a narrative fashion in
|
|
topical units. Readers looking for a complete description of a
|
|
particular command should look into <xref linkend="reference">.

|
The first few chapters are written so that they can be understood
|
|
without prerequisite knowledge, so that new users who need to set
|
|
up their own server can begin their exploration with this part.
|
|
The rest of this part which is about tuning and management
|
|
presupposes that the reader is familiar with the general use of
|
|
the <productname>PostgreSQL</> database system. Readers are
|
|
encouraged to look at <xref linkend="tutorial"> and <xref
|
|
linkend="sql"> for additional information.

This part describes the client programming interfaces distributed

with <productname>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 this part should be
|
|
familiar with using <acronym>SQL</acronym> commands to manipulate
|
|
and query the database (see <xref linkend="sql">) and of course
|
|
with the programming language that the interface uses.

|

This part 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 <productname>PostgreSQL</> has

|
been understood. This part also describes the server-side
|
|
programming languages available in the
|
|
<productname>PostgreSQL</productname> distribution as well as
|
|
general issues concerning server-side programming languages. This
|
|
information is only useful to readers that have read at least the
|
|
first few chapters of this part.
