I don't think you can do that anyway and we should not do it.  Shared
memory can be reset after a backend exits abnormally, but the
syslogger lives across that.  What you sent upthread to improve the
documentation is in my opinion sufficient:

I would not have split the paragraph you broke into two, but instead
just add this part in-between:
+       <para>
+        Permissions <literal>0640</literal> are recommended to be compatible with
+        <application>initdb</application> option <option>--allow-group-access</option>.
+       </para>
Any objections in doing that?
