FWIW, this was the only test that failed due to TMP being on a separate
partition.

I couldn't quite enable all tests (PG_TEST_EXTRA including libpq_encryption
fails due to some gssapi issue, kerberos fails due to paths being wrong / not
set up for windows, load_balance because I haven't set up hostnames), but I
don't think any of the issues around those tests are related.

I did also grep for other uses of tmpdir_short, they all seem to be
differently motivated.

I also looked for uses of rename() in tests. While
src/bin/pg_verifybackup/t/007_wal.pl does move stuff around, it afaict is
always going to be on the same filesystem.
