[OK, I'm bringing this back on-list, and bringing it to QingQing's
attention, who I secretly hope is the right person to be looking at this
problem :)]

Just to recap Marc and I have been looking at the performance disparity
between windows and linux for a single transaction statement by
statement insert on a very narrow table with no keys from a remote
client.  Marc's observations showed (and I verified) that windows is
much slower in this case than it should be.  I gprof'ed both the psql
client and the server during the insert and didn't see anything
seriously out of order...unfortunately QQ's latest win32 performance
tweaks haven't helped.

Marc's observation that by switching to a linux client drops time down
drastically is really intersing!
