doc: Improve {archive,restore}_command for compressed logs
The commands mentioned in the docs with gzip and gunzip did not prefix
the archives with ".gz" and used inconsistent paths for the archives,
which can be confusing.

If archive storage size is a concern, you can use
<application>gzip</application> to compress the archive files:
<programlisting>
-archive_command = 'gzip &lt; %p &gt; /var/lib/pgsql/archive/%f'
+archive_command = 'gzip &lt; %p &gt; /mnt/server/archivedir/%f.gz'
</programlisting>
You will then need to use <application>gunzip</application> during recovery:
<programlisting>
-restore_command = 'gunzip &lt; /mnt/server/archivedir/%f &gt; %p'
+restore_command = 'gunzip &lt; /mnt/server/archivedir/%f.gz &gt; %p'
</programlisting>
</para>
</sect3>
