There is no reference to TMPDIR in the pg_dump code.  It may be that
tmpfile() pays attention to such an environment variable on your
machine, but there's nothing about it in the Single Unix Spec.

Yeah.  I think it should specifically recommend custom format.  The only
reason for using tar format would be if you want to process the file
later with something other than pg_restore.
