I was just reading again this thread, and the suggestions that
current_logfiles is itself not a log file is also a sensible
position. I was just looking at the patch that you sent at the top of
the thread here:
https://www.postgresql.org/message-id/CAJrrPGcEotF1P7AWoeQyD3Pqr-0xkQg_Herv98DjbaMj+naozw@mail.gmail.com
And actually it seems to me that you have a race condition in that
stuff. I think that you had better use umask(), then fopen, and then
once again umask() to put back the previous permissions, removing the
extra chmod() call.
