Yeah, that's a well-known problem. It has been fixed in HEAD, cf
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=bed90759fcbcd72d4d06969eebab81e47326f9a2
and some follow-up patches. But unfortunately that's too invasive
for a back-patch, since it causes an ABI break for everything using
"struct stat". I don't think we'll be terribly interested in hacking
things to fix individual call sites instead, though.
