Current syslogger filename

Hello,

While going through the TODO items on the wiki I have come across the
following proposal:

Provide a way to query the log collector subprocess to determine the
name of the currently active log file

Current log files when rotating?
http://archives.postgresql.org/pgsql-general/2008-11/msg00418.php

Upon reading the related conversations, there doesn't seem to be a
consensus on how to implement this feature. If it is still relevant,
would you suggest a way to pass filename or time(which filename is
generated from) of the file from syslogger to inquiring postgres
instance.

Regards,

Kerem
