[ scratches head... ] If you aren't using any tablespaces, there should
be only *one* pgsql_tmp directory, which makes this even more confusing.
(Unless you're using a pre-8.3 release, in which case there would be one
per database, so maybe if you've got hundreds/thousands of databases in
the cluster that would explain it. But I sure hope you're not still
using pre-8.3, especially not on Windows.)
