Hi Hackers,
While investigating a possible file-descriptor issue, I enabled the
FDDEBUG code in src/backend/storage/file/fd.c, only to find that it
resulted in a crash as soon as it was invoked.
It turns out the crash was in some logging code that was being passed
a NULL fileName.
I've attached a small patch that corrects the issue.
