The <productname>&productname;</> &version; sources can be obtained from the

download section of our

website: <ulink url="http://www.postgresql.org/download/"></ulink>. You

should get a file named <filename>postgresql-&version;.tar.gz</filename>

or <filename>postgresql-&version;.tar.bz2</filename>. After

website: <ulink url="https://postgrespro.com/products/download"></ulink>. You

should get a file named <filename>postgrepro-&version;.tar.gz</filename>

or <filename>postgrespro-&version;.tar.bz2</filename>. After

you have obtained the file, unpack it:

<userinput>gunzippostgresql-&version;.tar.gz</userinput>

<userinput>tar xfpostgresql-&version;.tar</userinput>

<userinput>gunzippostgrepro-&version;.tar.gz</userinput>

<userinput>tar xfpostgrepro-&version;.tar</userinput>

</screen>

(Use <command>bunzip2</command> instead of <command>gunzip</command> if you

have the <filename>.bz2</filename> file.)

This will create a directory

<filename>postgresql-&version;</filename> under the current directory

<filename>postgrepro-&version;</filename> under the current directory

with the <productname>&productname;</> sources.

Change into that directory for the rest

of the installation procedure.

<title>Supported Platforms</title>

<para>

A platform (that is, a CPU architecture and operating system combination)

is considered supported by the PostgreSQL development

community if the code contains provisions to work on that platform and

it has recently been verified to build and pass its regression tests

on that platform. Currently, most testing of platform compatibility

is done automatically by test machines in the

<ulink url="https://buildfarm.postgresql.org/">PostgreSQL Build Farm</ulink>.

If you are interested in using <productname>&productname;</> on a platform

that is not represented in the build farm, but on which the code works

or can be made to work, you are strongly encouraged to set up a build

farm member machine so that continued compatibility can be assured.

</para>

<para>

In general, <productname>&productname;</> can be expected to work on

these CPU architectures: x86, x86_64, IA64, PowerPC,
