  Sorry for my 10*poor English ;-)
  I understand what you meant.


> There's already your pgbash that keeps backward compatibility.

  In the next release pgbash-2.1(pgbash is a tool like bash+psql),

    pgbash(7.0-libpq) can talk to 6.5/7.0-server.
and pgbash(6.5-libpq) can talk to 6.5/7.0-server.

  pgbash will keep backward and forward compatibility as much as 
possible.
