On my HPUX box, the man page disapproves of both, calling them obsolete
(and this man page is old enough to vote, I believe...)
Everywhere else that we need to do something like this, we just use our
own PID to disambiguate, iesprintf(tempfilename, "/path/to/file.%d", (int) getpid());
There is no need to deviate from that pattern or introduce portability
issues, since we can reasonably assume that no non-Postgres programs are
creating files in this directory.
