Log message:
	libpq can now talk to either 3.0 or 2.0 protocol servers.  It first tries
	protocol 3, then falls back to 2 if postmaster rejects the startup packet
	with an old-format error message.  A side benefit of the rewrite is that
	SSL-encrypted connections can now be made without blocking.  (I think,
	anyway, but do not have a good way to test.)
