  3.     On some systems with shared libraries

  4.     you need to tell the system how to find the newly installed

  5.     shared libraries.  The systems on which this is

  6.     <span class="emphasis"><em>not</em></span> necessary include

  7.     <span class="systemitem">FreeBSD</span>,

  8.     <span class="systemitem">HP-UX</span>,

  9.     <span class="systemitem">Linux</span>,

  10.     <span class="systemitem">NetBSD</span>, <span class="systemitem">OpenBSD</span>, and

  11.     <span class="systemitem">Solaris</span>.

  12.    </p><p>

  13.     The method to set the shared library search path varies between

  14.     platforms, but the most widely-used method is to set the

  15.     environment variable <code class="envar">LD_LIBRARY_PATH</code> like so: In Bourne

  16.     shells (<code class="command">sh</code>, <code class="command">ksh</code>, <code class="command">bash</code>, <code class="command">zsh</code>):

  17. </p><pre class="programlisting">

  18. LD_LIBRARY_PATH=/usr/local/pgsql/lib

  19. export LD_LIBRARY_PATH

  20. </pre><p>

  21.     or in <code class="command">csh</code> or <code class="command">tcsh</code>:

  22. </p><pre class="programlisting">

  23. setenv LD_LIBRARY_PATH /usr/local/pgsql/lib

  24. </pre><p>

  25.     Replace <code class="literal">/usr/local/pgsql/lib</code> with whatever you set

  26.     <code class="option"><code class="literal">--libdir</code></code> to in <a class="xref" href="install-procedure.html#CONFIGURE" title="Configuration">Step 1</a>.

  27.     You should put these commands into a shell start-up file such as

  28.     <code class="filename">/etc/profile</code> or <code class="filename">~/.bash_profile</code>.  Some

  29.     good information about the caveats associated with this method can

  30.     be found at <a class="ulink" href="http://xahlee.info/UnixResource_dir/_/ldpath.html" target="_top">http://xahlee.info/UnixResource_dir/_/ldpath.html</a>.

  31.    </p><p>

  32.     On some systems it might be preferable to set the environment

  33.     variable <code class="envar">LD_RUN_PATH</code> <span class="emphasis"><em>before</em></span>

  34.     building.

  35.    </p><p>

  36.     On <span class="systemitem">Cygwin</span>, put the library

  37.     directory in the <code class="envar">PATH</code> or move the

  38.     <code class="filename">.dll</code> files into the <code class="filename">bin</code>

  39.     directory.

  40.    </p><p>

  41.     If in doubt, refer to the manual pages of your system (perhaps

  42.     <code class="command">ld.so</code> or <code class="command">rld</code>). If you later

  43.     get a message like:

  44. </p><pre class="screen">

  45. psql: error in loading shared libraries

  46. libpq.so.2.1: cannot open shared object file: No such file or directory

  47. </pre><p>

  48.     then this step was necessary.  Simply take care of it then.

  49.    </p><p>

  50.     <a id="id-1.6.3.9.2.8.1" class="indexterm"></a>

  51.     If you are on <span class="systemitem">Linux</span> and you have root

  52.     access, you can run:

  53. </p><pre class="programlisting">

  54. /sbin/ldconfig /usr/local/pgsql/lib

  55. </pre><p>

  56.     (or equivalent directory) after installation to enable the

  57.     run-time linker to find the shared libraries faster.  Refer to the

  58.     manual page of <code class="command">ldconfig</code> for more information.  On

  59.     <span class="systemitem">FreeBSD</span>, <span class="systemitem">NetBSD</span>, and <span class="systemitem">OpenBSD</span> the command is:

  60. </p><pre class="programlisting">

  61. /sbin/ldconfig -m /usr/local/pgsql/lib

  62. </pre><p>

  63.     instead.  Other systems are not known to have an equivalent

  64.     command.

  65.    </p></div><div class="sect2" id="id-1.6.3.9.3"><div class="titlepage"><div><div><h3 class="title">16.5.2. Environment Variables</h3></div></div></div><a id="id-1.6.3.9.3.2" class="indexterm"></a><p>

  66.     If you installed into <code class="filename">/usr/local/pgsql</code> or some other

  67.     location that is not searched for programs by default, you should

  68.     add <code class="filename">/usr/local/pgsql/bin</code> (or whatever you set

  69.     <code class="option"><code class="literal">--bindir</code></code> to in <a class="xref" href="install-procedure.html#CONFIGURE" title="Configuration">Step 1</a>)

  70.     into your <code class="envar">PATH</code>.  Strictly speaking, this is not

  71.     necessary, but it will make the use of <span class="productname">PostgreSQL</span>

  72.     much more convenient.

  73.    </p><p>

  74.     To do this, add the following to your shell start-up file, such as

  75.     <code class="filename">~/.bash_profile</code> (or <code class="filename">/etc/profile</code>, if you

  76.     want it to affect all users):

  77. </p><pre class="programlisting">

  78. PATH=/usr/local/pgsql/bin:$PATH

  79. export PATH

  80. </pre><p>

  81.     If you are using <code class="command">csh</code> or <code class="command">tcsh</code>, then use this command:

  82. </p><pre class="programlisting">

  83. set path = ( /usr/local/pgsql/bin $path )

  84. </pre><p>

  85.    </p><p>

  86.     <a id="id-1.6.3.9.3.5.1" class="indexterm"></a>

  87.     To enable your system to find the <span class="application">man</span>

  88.     documentation, you need to add lines like the following to a

  89.     shell start-up file unless you installed into a location that is

  90.     searched by default:

  91. </p><pre class="programlisting">

  92. MANPATH=/usr/local/pgsql/share/man:$MANPATH

  93. export MANPATH

  94. </pre><p>

  95.    </p><p>

  96.     The environment variables <code class="envar">PGHOST</code> and <code class="envar">PGPORT</code>

  97.     specify to client applications the host and port of the database

  98.     server, overriding the compiled-in defaults. If you are going to

  99.     run client applications remotely then it is convenient if every

  100.     user that plans to use the database sets <code class="envar">PGHOST</code>.  This

  101.     is not required, however; the settings can be communicated via command

  102.     line options to most client programs.
