We did maintain compatibility, in that the server will still talk to
a client that identifies itself as 1.0 in the initial handshake.
(Kudos to whoever had the foresight to put a protocol version number
in the startup message, BTW.)
As things are currently set up, however, a new compilation of libpq
will only know how to talk protocol 2.0, so it cannot be used to
talk to an old server. Are you concerned about that? I don't see
any easy way around it...
