We don't currently support 64-bit builds on Windows. There are a pile
of issues there, most coming from Microsoft's nonstandard decision to
make sizeof(long) != sizeof(pointer). In practice you probably wouldn't
get any noticeable performance improvement over a 32-bit build anyway,
seeing that large shared_buffers settings don't seem to be useful on
Windows.
