Couple of quick protocol questions:

1) What encoding is used for strings sent and received during the 
startup phase? I can set client_encoding to a known value as a parameter 
in the startup packet, but the protocol spec doesn't appear to say how 
the startup packet itself and the various strings sent/received during 
startup (e.g. authentication, error messages) are encoded.

2) At what point in the stream does a client_encoding change take effect 
-- immediately after the corresponding ParameterStatus message, or at 
some other point?
