It means there's something pretty broken about your networking setup :-(
The stats collection code tries to set up a UDP socket connected to
itself as a means of forwarding statistics from individual backend
processes to the stats collector subprocess. AFAICS there is no
good reason that a connection attempt to an existing UDP socket on
127.0.0.1 should ever fail, but evidently you've managed to configure
your system so that it does. (Overly aggressive packet filtering,
perhaps? Or is this just another cygwin/Windows bug?)
If you can't figure out how to get the connection to work, you can
turn off the "start statistics collector" postgresql.conf option to
bypass the problem.
