There was a recent thread that came to the conclusion that loopback TCP
connections are remarkably slow on Windows unless you've installed the
correct add-on package --- something not tremendously obvious, I think
it was a "QOS" patch or maybe something to do with packet filtering.
Check the archives of the various pgsql lists.  I forget which list but
it was just a couple weeks ago.
