Stephen, could you apply Hari's patch then? I am not sure what the
consensus is, but documenting the restriction is the minimum we can
do.
- The default permissions are <literal>0600</literal>, meaning only the
- server owner can read or write the log files. The other commonly
- useful setting is <literal>0640</literal>, allowing members of the owner's
- group to read the files. Note however that to make use of such a
- setting, you'll need to alter <xref linkend="guc-log-directory"/> to
- store the files somewhere outside the cluster data directory. In
- any case, it's unwise to make the log files world-readable, since
- they might contain sensitive data.

I would formulate that differently, by just adding an extra paragraph
to mention that using <literal>0640</literal> is recommended to be
compatible with initdb's --allow-group-access instead of sticking it
on the middle of the existing paragraph.
