   In general, a modern Unix-compatible platform should be able to run
   <productname>PostgreSQL</>.
    The platforms that had received specific testing at the
   time of release are listed in <xref linkend="supported-platforms">

      <acronym>GNU</> <application>make</> is often installed under

      refer to it by that name. (On some systems
      <acronym>GNU</acronym> <application>make</> is the default tool with the name

      <application>make</application> enter

   The following packages are optional.  They are not required in the

   options are enabled, as explained below.

   <itemizedlist>
    <listitem>
     <para>
      To build the server programming language
      <application>PL/Perl</application> you need a full
      <productname>Perl</productname> installation, including the
      <filename>libperl</filename> library and the header files.
      Since <application>PL/Perl</application> will be a shared
      library, the <indexterm><primary>libperl</primary></indexterm>
      <filename>libperl</filename> library must be a shared library
      also on most platforms.  This appears to be the default in
      recent <productname>Perl</productname> versions, but it was not
      in earlier versions, and in general it is the choice of whomever
      installed Perl at your site.
     </para>

     <para>
      If you don't have the shared library but you need one, a message
      like this will appear during the build to point out this fact:
<screen>
*** Cannot build PL/Perl because libperl is not a shared library.
*** You might have to rebuild your Perl installation.  Refer to
*** the documentation for details.
</screen>
      (If you don't follow the on-screen output you will merely notice
      that the <application>PL/Perl</application> library object,
      <filename>plperl.so</filename> or similar, will not be
      installed.)  If you see this, you will have to rebuild and
      install <productname>Perl</productname> manually to be able to
      build <application>PL/Perl</application>.  During the
      configuration process for <productname>Perl</productname>,
      request a shared library.
     </para>
    </listitem>

    <listitem>
     <para>
      To build the <application>PL/Python</> server programming
      language, you need a <productname>Python</productname>
      installation with the header files and the <application>distutils</application> module.
      The <application>distutils</application> module is included by default with
      <productname>Python</productname> 1.6 and later; users of
      earlier versions of <productname>Python</productname> will need
      to install it.
     </para>

     <para>
      Since <application>PL/Python</application> will be a shared
      library, the <indexterm><primary>libpython</primary></indexterm>
      <filename>libpython</filename> library must be a shared library
      also on most platforms.  This is not the case in a default
      <productname>Python</productname> installation.  If after
      building and installing you have a file called
      <filename>plpython.so</filename> (possibly a different
      extension), then everything went well.  Otherwise you should
      have seen a notice like this flying by:
<screen>
*** Cannot build PL/Python because libpython is not a shared library.
*** You might have to rebuild your Python installation.  Refer to
*** the documentation for details.
</screen>
      That means you have to rebuild (part of) your
      <productname>Python</productname> installation to supply this
      shared library.
     </para>

     <para>
      If you have problems, run <productname>Python</> 2.3 or later's
      configure using the <literal>--enable-shared</> flag.  On some
      operating systems you don't have to build a shared library, but
      you will have to convince the <productname>PostgreSQL</> build
      system of this.  Consult the <filename>Makefile</filename> in
      the <filename>src/pl/plpython</filename> directory for details.

      To enable Native Language Support (<acronym>NLS</acronym>), that
      is, the ability to display a program's messages in a language
      other than English, you need an implementation of the
      <application>Gettext</> <acronym>API</acronym>.  Some operating
      systems have this built-in (e.g., <systemitem
      class="osname">Linux</>, <systemitem class="osname">NetBSD</>,
      <systemitem class="osname">Solaris</>), for other systems you
      can download an add-on package from here: <ulink
      url="http://developer.postgresql.org/~petere/bsd-gettext/" ></ulink>.
      If you are using the <application>Gettext</> implementation in
      the <acronym>GNU</acronym> C library then you will additionally
      need the <productname>GNU Gettext</productname> package for some
      utility programs.  For any of the other implementations you will
      not need it.

   If you are building from a <acronym>CVS</acronym> tree instead of

      </indexterm>

      <application>Flex</> and <application>Bison</>
      are needed to build a CVS checkout or if you changed the actual
      scanner and parser definition files. If you need them, be sure
      to get <application>Flex</> 2.5.4 or later and
      <application>Bison</> 1.875 or later. Other <application>yacc</>
      programs can sometimes be used, but doing so requires extra
      effort and is not recommended. Other <application>lex</>
      programs will definitely not work.
     </para>
    </listitem>
   </itemizedlist>
  </para>

  <para>
   If you need to get a <acronym>GNU</acronym> package, you can find
   it at your local <acronym>GNU</acronym> mirror site (see <ulink
   url="http://www.gnu.org/order/ftp.html"></>
   for a list) or at <ulink
   url="ftp://ftp.gnu.org/gnu/"></ulink>.
  </para>

  <para>
   Also check that you have sufficient disk space. You will need about
   65 MB for the source tree during compilation and about 15 MB for
   the installation directory. An empty database cluster takes about
   25 MB, databases take about five times the amount of space that a
   flat text file with the same data would take. If you are going to
   run the regression tests you will temporarily need up to an extra
   90 MB. Use the <command>df</command> command to check for disk
   space.

   The internal data storage format changes with new releases of
   <productname>PostgreSQL</>. Therefore, if you are upgrading an

   <quote>&majorversion;.x</quote>, you must back up and restore your

   Substitute your paths appropriately.

    <para>
     Make sure that your database is not updated during or after the
     backup. This does not affect the integrity of the backup, but the
     changed data would of course not be included. If necessary, edit

     if you need to do this.

    <para>
     To make the backup, you can use the <application>pg_dumpall</application>
     command from the version you are currently running.  For best
     results, however, try to use the <application>pg_dumpall</application>
     command from <productname>PostgreSQL</productname> &version;,
     since this version contains bug fixes and improvements over older
     versions.  While this advice might seem idiosyncratic since you
     haven't installed the new version yet, it is advisable to follow
     it if you plan to install the new version in parallel with the
     old version.  In that case you can complete the installation
     normally and transfer the data later.  This will also decrease
     the downtime.
    </para>
   </step>

   <step>
    <para>
     If you are installing the new version at the same location as the
     old one then shut down the old server, at the latest before you
     install the new files:
<screen>
<userinput>kill -INT `cat /usr/local/pgsql/data/postmaster.pid | sed 1q`</>
</screen>
     Versions prior to 7.0 do not have this
     <filename>postmaster.pid</> file. If you are using such a version
     you must find out the process ID of the server yourself, for
     example by typing <userinput>ps ax | grep postmaster</>, and
     supply it to the <command>kill</> command.
    </para>

    <para>
     On systems that have <productname>PostgreSQL</> started at boot time, there is
     probably a start-up file that will accomplish the same thing. For
     example, on a <systemitem class="osname">Red Hat Linux</> system one might find that
<screen>
<userinput>/etc/rc.d/init.d/postgresql stop</userinput>

     If you are installing in the same place as the old version then
     it is also a good idea to move the old installation out of the

   <para>
    The first step of the installation procedure is to configure the
    source tree for your system and choose the options you would like.
    This is done by running the <filename>configure</> script. For a
    default installation simply enter
<screen>
<userinput>./configure</userinput>
</screen>
    This script will run a number of tests to guess values for various
    system dependent variables and detect some quirks of your
    operating system, and finally will create several files in the
    build tree to record what it found.  (You can also run
    <filename>configure</filename> in a directory outside the source
    tree if you want to keep the build directory separate.)
   </para>

   <para>
    The default configuration will build the server and utilities, as
    well as all client applications and interfaces that require only a
    C compiler. All files will be installed under
    <filename>/usr/local/pgsql</> by default.
   </para>

   <para>
    You can customize the build and installation process by supplying one
    or more of the following command line options to
    <filename>configure</filename>:

        <para>
         Install all files under the directory <replaceable>PREFIX</>
         instead of <filename>/usr/local/pgsql</filename>. The actual
         files will be installed into various subdirectories; no files
         will ever be installed directly into the
         <replaceable>PREFIX</> directory.
        </para>

        <para>
         If you have special needs, you can also customize the
         individual subdirectories with the following options. However,
         if you leave these with their defaults, the installation will be
         relocatable, meaning you can move the directory after
         installation. (The <literal>man</> and <literal>doc</>
         locations are not affected by this.)
        </para>

        <para>
         For relocatable installs, you might want to use 
         <filename>configure</filename>'s <literal>--disable-rpath</>
         option.  Also, you will need to tell the operating system how

         share architecture-independent files between hosts. If you

         <replaceable>PREFIX</> and both architecture-dependent and

       Care has been taken to make it possible to install
       <productname>PostgreSQL</> into shared installation locations
       (such as <filename>/usr/local/include</filename>) without
       interfering with the namespace of the rest of the system. First,
       the string <quote><literal>/postgresql</literal></quote> is
       automatically appended to <varname>datadir</varname>,
       <varname>sysconfdir</varname>, and <varname>docdir</varname>,
       unless the fully expanded directory name already contains the
       string <quote><literal>postgres</></quote> or
       <quote><literal>pgsql</></quote>. For example, if you choose
       <filename>/usr/local</filename> as prefix, the documentation will
       be installed in <filename>/usr/local/doc/postgresql</filename>,
       but if the prefix is <filename>/opt/postgres</filename>, then it
       will be in <filename>/opt/postgres/doc</filename>. The public C
       header files of the client interfaces are installed into
       <varname>includedir</varname> and are namespace-clean. The
       internal header files and the server header files are installed
       into private directories under <varname>includedir</varname>. See
       the documentation of each interface for information about how to
       get at the its header files. Finally, a private subdirectory will
       also be created, if appropriate, under <varname>libdir</varname>
       for dynamically loadable modules.

   <para>
    On some systems that have shared libraries (which most systems do)
    you need to tell your system how to find the newly installed
    shared libraries.  The systems on which this is
    <emphasis>not</emphasis> necessary include <systemitem
    class="osname">BSD/OS</>, <systemitem class="osname">FreeBSD</>,
    <systemitem class="osname">HP-UX</>, <systemitem

    UNIX</> (formerly <systemitem class="osname">Digital UNIX</>), and
    <systemitem class="osname">Solaris</>.
   </para>

   <para>
    The method to set the shared library search path varies between
    platforms, but the most widely usable method is to set the
    environment variable <envar>LD_LIBRARY_PATH</> like so: In Bourne
    shells (<command>sh</>, <command>ksh</>, <command>bash</>, <command>zsh</>)
<programlisting>
LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH
</programlisting>
    or in <command>csh</> or <command>tcsh</>
<programlisting>
setenv LD_LIBRARY_PATH /usr/local/pgsql/lib
</programlisting>
    Replace <literal>/usr/local/pgsql/lib</> with whatever you set
    <option><literal>--libdir</></> to in <xref linkend="configure">.
    You should put these commands into a shell start-up file such as
    <filename>/etc/profile</> or <filename>~/.bash_profile</>.  Some
    good information about the caveats associated with this method can
    be found at <ulink
    url="http://www.visi.com/~barr/ldpath.html"></ulink>.

<programlisting>
/sbin/ldconfig /usr/local/pgsql/lib
</programlisting>
    (or equivalent directory) after installation to enable the
    run-time linker to find the shared libraries faster.  Refer to the

    If you installed into <filename>/usr/local/pgsql</> or some other
    location that is not searched for programs by default, you should
    add <filename>/usr/local/pgsql/bin</> (or whatever you set
    <option><literal>--bindir</></> to in <xref linkend="configure">)
    into your <envar>PATH</>.  Strictly speaking, this is not
    necessary, but it will make the use of <productname>PostgreSQL</>
    much more convenient.
   </para>

   <para>
    To do this, add the following to your shell start-up file, such as
    <filename>~/.bash_profile</> (or <filename>/etc/profile</>, if you
    want it to affect every user):
<programlisting>
PATH=/usr/local/pgsql/bin:$PATH
export PATH
</programlisting>
    If you are using <command>csh</> or <command>tcsh</>, then use this command:
<programlisting>
set path = ( /usr/local/pgsql/bin $path )
</programlisting>
   </para>

    <indexterm>
     <primary><envar>MANPATH</envar></primary>

    To enable your system to find the <application>man</>
    documentation, you need to add lines like the following to a
    shell start-up file unless you installed into a location that is
    searched by default.
<programlisting>
MANPATH=/usr/local/pgsql/man:$MANPATH
export MANPATH
</programlisting>

   <para>
    The environment variables <envar>PGHOST</> and <envar>PGPORT</>
    specify to client applications the host and port of the database
    server, overriding the compiled-in defaults. If you are going to
    run client applications remotely then it is convenient if every
    user that plans to use the database sets <envar>PGHOST</>.  This
    is not required, however: the settings can be communicated via command
    line options to most client programs.

  <title>Getting Started</title>

  <para>
   The following is a quick summary of how to get <productname>PostgreSQL</> up and
   running once installed. The main documentation contains more information.
  </para>

  <procedure>
   <step>
    <para>
     Create a user account for the <productname>PostgreSQL</>
     server. This is the user the server will run as. For production
     use you should create a separate, unprivileged account
     (<quote>postgres</> is commonly used). If you do not have root
     access or just want to play around, your own user account is
     enough, but running the server as root is a security risk and
     will not work.
<screen>
<userinput>adduser postgres</>
</screen>
    </para>
   </step>

   <step>
    <para>
     Create a database installation with the <command>initdb</>
     command. To run <command>initdb</> you must be logged in to your
     <productname>PostgreSQL</> server account. It will not work as
     root.
<screen>
root# <userinput>mkdir /usr/local/pgsql/data</>
root# <userinput>chown postgres /usr/local/pgsql/data</>
root# <userinput>su - postgres</>
postgres$ <userinput>/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data</>
</screen>
    </para>

    <para>
     The <option>-D</> option specifies the location where the data
     will be stored. You can use any path you want, it does not have
     to be under the installation directory. Just make sure that the
     server account can write to the directory (or create it, if it
     doesn't already exist) before starting <command>initdb</>, as
     illustrated here.
    </para>
   </step>

   <step>
    <para>
     The previous step should have told you how to start up the
     database server. Do so now. The command should look something
     like
<programlisting>
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
</programlisting>
     This will start the server in the foreground. To put the server
     in the background use something like
<programlisting>
nohup /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data \
    &lt;/dev/null &gt;&gt;server.log 2&gt;&amp;1 &lt;/dev/null &amp;
</programlisting>
    </para>

    <para>
     To stop a server running in the background you can type
<programlisting>
kill `cat /usr/local/pgsql/data/postmaster.pid`
</programlisting>
    </para>

    <para>
     In order to allow TCP/IP connections (rather than only Unix
     domain socket ones) you need to pass the <option>-i</> option to
     <filename>postmaster</>.
    </para>
   </step>

   <step>
    <para>
     Create a database:
<screen>
<userinput>createdb testdb</>
</screen>
     Then enter
<screen>
<userinput>psql testdb</>
</screen>
     to connect to that database. At the prompt you can enter SQL
     commands and start experimenting.
    </para>
   </step>
  </procedure>

  <para>
   <itemizedlist>
    <listitem>
     <para>
      The <productname>PostgreSQL</> distribution contains a
      comprehensive documentation set, which you should read sometime.
      After installation, the documentation can be accessed by
      pointing your browser to
      <filename>/usr/local/pgsql/doc/html/index.html</>, unless you
      changed the installation directories.
     </para>

     <para>
      The first few chapters of the main documentation are the Tutorial,
      which should be your first reading if you are completely new to
      <acronym>SQL</> databases.  If you are familiar with database
      concepts then you want to proceed with part on server
      administration, which contains information about how to set up
      the database server, database users, and authentication.
     </para>
    </listitem>

    <listitem>
     <para>
      Usually, you will want to modify your computer so that it will
      automatically start the database server whenever it boots. Some
      suggestions for this are in the documentation.
     </para>
    </listitem>

    <listitem>
     <para>
      Run the regression tests against the installed server (using
      <command>gmake installcheck</command>). If you didn't run the
      tests before installation, you should definitely do it now. This
      is also explained in the documentation.
     </para>
    </listitem>

    <listitem>
     <para>
      By default, <productname>PostgreSQL</> is configured to run on
      minimal hardware.  This allows it to start up with almost any
      hardware configuration. The default configuration is, however,
      not designed for optimum performance. To achieve optimum
      performance, several server parameters must be adjusted, the two
      most common being <varname>shared_buffers</varname> and
      <varname>work_mem</varname>.
      Other parameters mentioned in the documentation also affect
      performance.

  <title>Supported Platforms</title>

  <para>
   <productname>PostgreSQL</> has been verified by the developer
   community to work on the platforms listed below. A supported
   platform generally means that <productname>PostgreSQL</> builds and
   installs according to these instructions and that the regression
   tests pass.  <quote>Build farm</quote> entries refer to builds
   reported by the <ulink url="http://www.pgbuildfarm.org/">PostgreSQL

   <para>
    The following platforms are either known not to work, or they used
    to work in a previous release and we did not receive explicit
    confirmation of a successful test with version &majorversion; at
    the time this list was compiled.  We include these here to let you
    know that these platforms <emphasis>could</> be supported if given
    some attention.
