Hello everyone:
My $0.02: Don't bother supporting FAT at all.
I believe anywone who wants to install PostgreSQL on NT5+ would either have
an NTFS partition, or be able to create/convert one easily.
From

> A partition can also be converted after Setup by using Convert.exe.
> For more information about Convert.exe, after completing Setup, click
> Start, click Run, type cmd, and then press ENTER. In the command
> window, type help convert, and then press ENTER.
