Here is the v13 of the patch, it applies your last change in comment and
some other changes:

- I've reverted the patch removing the call to logfile_writename in
open_csvlogfile function, it is required to write log filename at
startup when log_destination is set to csvlog. I could not find a better
place right now, but will try to see if we can avoid the call to
logfile_writename().
- Do not write current_logfiles when log_collector is activated but
log_destination doesn't contained stderr or csvlog. This was creating an
empty file that can confuse the user.
- I've changed the comment in doc/src/sgml/storage.sgml by addind the
following sentence: "This file is present only when logging_collector is
activated and when at least one of stderr or csvlog value is present in
log_destination."
