On some systems with shared libraries
you need to tell the system how to find the newly installed
shared libraries. The systems on which this is
<span class="emphasis"><em>not</em></span> necessary include
<span class="systemitem">FreeBSD</span>,
<span class="systemitem">Linux</span>,
<span class="systemitem">NetBSD</span>, <span class="systemitem">OpenBSD</span>, and
<span class="systemitem">Solaris</span>.
</p><p>
The method to set the shared library search path varies between
platforms, but the most widely-used method is to set the
environment variable <code class="envar">LD_LIBRARY_PATH</code> like so: In Bourne
shells (<code class="command">sh</code>, <code class="command">ksh</code>, <code class="command">bash</code>, <code class="command">zsh</code>):
</p><pre class="programlisting">
LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH
</pre><p>
or in <code class="command">csh</code> or <code class="command">tcsh</code>:
</p><pre class="programlisting">
setenv LD_LIBRARY_PATH /usr/local/pgsql/lib
</pre><p>
Replace <code class="literal">/usr/local/pgsql/lib</code> with whatever you set
<code class="option"><code class="literal">--libdir</code></code> to in <a class="xref" href="install-make.html#CONFIGURE" title="Configuration">Step 1</a>.
You should put these commands into a shell start-up file such as
<code class="filename">/etc/profile</code> or <code class="filename">~/.bash_profile</code>. Some
good information about the caveats associated with this method can
be found at <a class="ulink" href="http://xahlee.info/UnixResource_dir/_/ldpath.html" target="_top">http://xahlee.info/UnixResource_dir/_/ldpath.html</a>.
</p><p>
On some systems it might be preferable to set the environment
variable <code class="envar">LD_RUN_PATH</code> <span class="emphasis"><em>before</em></span>
building.
</p><p>
On <span class="systemitem">Cygwin</span>, put the library
directory in the <code class="envar">PATH</code> or move the
<code class="filename">.dll</code> files into the <code class="filename">bin</code>
directory.
</p><p>
If in doubt, refer to the manual pages of your system (perhaps
<code class="command">ld.so</code> or <code class="command">rld</code>). If you later
get a message like:
</p><pre class="screen">
psql: error in loading shared libraries
libpq.so.2.1: cannot open shared object file: No such file or directory
</pre><p>
then this step was necessary. Simply take care of it then.
</p><p>
<a id="id-1.6.4.9.2.8.1" class="indexterm"></a>
If you are on <span class="systemitem">Linux</span> and you have root
access, you can run:
</p><pre class="programlisting">
/sbin/ldconfig /usr/local/pgsql/lib
</pre><p>
(or equivalent directory) after installation to enable the
run-time linker to find the shared libraries faster. Refer to the
manual page of <code class="command">ldconfig</code> for more information. On
<span class="systemitem">FreeBSD</span>, <span class="systemitem">NetBSD</span>, and <span class="systemitem">OpenBSD</span> the command is:
</p><pre class="programlisting">
/sbin/ldconfig -m /usr/local/pgsql/lib
</pre><p>
instead. Other systems are not known to have an equivalent
command.

If you installed into <code class="filename">/usr/local/pgsql</code> or some other
location that is not searched for programs by default, you should
add <code class="filename">/usr/local/pgsql/bin</code> (or whatever you set
<code class="option"><code class="literal">--bindir</code></code> to in <a class="xref" href="install-make.html#CONFIGURE" title="Configuration">Step 1</a>)
into your <code class="envar">PATH</code>. Strictly speaking, this is not
necessary, but it will make the use of <span class="productname">PostgreSQL</span>
much more convenient.
</p><p>
To do this, add the following to your shell start-up file, such as
<code class="filename">~/.bash_profile</code> (or <code class="filename">/etc/profile</code>, if you
want it to affect all users):
</p><pre class="programlisting">
PATH=/usr/local/pgsql/bin:$PATH
export PATH
</pre><p>
If you are using <code class="command">csh</code> or <code class="command">tcsh</code>, then use this command:
</p><pre class="programlisting">
set path = ( /usr/local/pgsql/bin $path )
</pre><p>
</p><p>
<a id="id-1.6.4.9.3.5.1" class="indexterm"></a>
To enable your system to find the <span class="application">man</span>
documentation, you need to add lines like the following to a
shell start-up file unless you installed into a location that is
searched by default:
</p><pre class="programlisting">
MANPATH=/usr/local/pgsql/share/man:$MANPATH
export MANPATH
</pre><p>
</p><p>
The environment variables <code class="envar">PGHOST</code> and <code class="envar">PGPORT</code>
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 <code class="envar">PGHOST</code>. This
is not required, however; the settings can be communicated via command
line options to most client programs.
