You either need something that ssh tunnelling/netcat CANNOT do for you, or you don't understand that ssh tunnelling/netcat are sufficient for what you need to do. It's not clear which of those it is. Why don't you describe the requirement at a lower level (e.g., what are the two computers you've got, what is between the two computers [is there a firewall, is the other computer on the other side of the world from you], etc). As it is, your problem statement is too high level. You're assuming that you need to write your own proxy. Consider lower level solutions. Or are you writing a proxy for fun? If so, how is the proxy supposed to work? you run psql at the local box, it connects to the proxy, and the proxy passes everything over to the remote box? ssh/netcat will do that for you. What other reasons do you have for writing your own proxy? The only thing I can think of is sniffing the passwords of other users, but I'm sure there are other interesting things you might be trying to do.
