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.
