It is documented. AuthenticationUnencryptedPassword is the pre-7.2 name
for AuthenticationCleartextPassword. They are the same message
(char 'R', int 3) but the name changed at 7.2.

Sounds like you are doing it right, but you'll probably need to use
tcpdump or something similar to find out what is really going on.
I wrote a client in Tcl which talks right to the backend, and it does
what you said: send startup packet, get ('R',3) back, send password,
get AuthenticationOK ('R',0) back.
