I think you might have a conceptual error here.  The salt is sent
from the server to you, not the other way around.  It's just four
random bytes in the AuthenticationMD5Password message, which I'm
pretty sure you should incorporate verbatim in your MD5 input.

The bytes are just binary data, they're not ASCII or encoded
in some way.

            regards, tom lane
