If archive storage size is a concern, use <application>pg_compresslog</>,

<ulink url="http://pglesslog.projects.postgresql.org"></ulink>, to

remove unnecessary <xref linkend="guc-full-page-writes"> and trailing

space from the WAL files. You can then use

<application>gzip</application> to further compress the output of

<application>pg_compresslog</>:

<programlisting>

archive_command = 'pg_compresslog %p - | gzip &gt; /var/lib/pgsql/archive/%f'

</programlisting>

You will then need to use <application>gunzip</> and

<application>pg_decompresslog</> during recovery:

<programlisting>

restore_command = 'gunzip &lt; /mnt/server/archivedir/%f | pg_decompresslog - %p'

</programlisting>
