Hmm,sorry for my poor English.
What I meant is a little different from yours.
What I wanted was to know official opinions about backward
compatibility of clients(not only psql)included in PostgreSQL's
release.

As for psql it isn't a generic client software as Peter mentioned.
It's a part of backend in a sense. At least it could talk to pre-7.0
backend and it isn't so critical that \l,\df and \dd doesn't work for
pre-7.0 backends. I'm not so much eager to change psql myself.

There's already your pgbash that keeps backward compatibility.
