The given archive_command example didn't use %p or %f, which wouldn't
really work in practice.
<varname>archive_command</varname>, so that their
<filename>postgresql.conf</> entry looks very simple:
<programlisting>
-archive_command = 'local_backup_script.sh'
+archive_command = 'local_backup_script.sh "%p" "%f"'
</programlisting>
Using a separate script file is advisable any time you want to use
more than a single command in the archiving process.
