I'm not sure if you already know this, but Cygwin Unix sockets are
actually implemented as TCP/IP sockets.  Anyway, I forced TCP connections
and got the same psql hang:

(gdb) p *conn
$1 = {pghost = 0xa016618 "localhost", pghostaddr = 0x0,
  pgport = 0xa016628 "65432", pgunixsocket = 0x0, pgtty = 0xa016638 "",
  pgoptions = 0xa016648 "", dbName = 0xa017188 "regression",
  pguser = 0xa017168 "jt", pgpass = 0xa017178 "", Pfdebug = 0x0,
  noticeHook = 0x67984e8c <defaultNoticeProcessor>, noticeArg = 0x0,
  status = CONNECTION_STARTED, asyncStatus = PGASYNC_IDLE,
  notifyList = 0xa0103e8, sock = 3, laddr = {sa = {sa_family = 0,
      sa_data = '\000' <repeats 13 times>}, in = {sin_family = 0,
      sin_port = 0, sin_addr = {s_addr = 0},
      __pad = "\000\000\000\000\000\000\000"}, un = {sun_family = 0,
      sun_path = '\000' <repeats 107 times>}}, raddr = {sa = {sa_family = 2,
      sa_data = "ÿ\230\177\000\000\001\000\000\000\000\000\000\000"}, in = {
      sin_family = 2, sin_port = 39167, sin_addr = {s_addr = 16777343},
      __pad = "\000\000\000\000\000\000\000"}, un = {sun_family = 2,
      sun_path = "ÿ\230\177\000\000\001", '\000' <repeats 101 times>}},
  raddr_len = 16, be_pid = 0, be_key = 0, salt = "\000", lobjfuncs = 0x0,
  inBuffer = 0xa0103f8 "", inBufSize = 16384, inStart = 0, inCursor = 0,
  inEnd = 0, nonblocking = 0, outBuffer = 0xa014400 "", outBufSize = 8192,
  outCount = 0, result = 0x0, curTuple = 0x0,
  setenv_state = SETENV_STATE_IDLE, next_eo = 0x0, errorMessage = {
    data = 0xa016408 "", len = 0, maxlen = 256}, workBuffer = {
    data = 0xa016510 "", len = 0, maxlen = 256}, client_encoding = 0}

Any ideas on how to demonstrate this to the Cygwin community without
all of the PostgreSQL baggage.  Sorry, but I'm not very experienced
with sockets.

Thanks,
Jason
