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:
https://www.postgresql.org/message-id/CAJrrPGe-v2_LMFD9nHrBEjJy3vVOKJwY3w_h+Fs2nxCJg3PbaA@mail.gmail.com
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?
