The ALTER ROLE *does* take effect ... and then psql overrides it from
the environment. Not sure why you expected differently --- psql doesn't
especially care why the server sent the initial client_encoding that it
did.
BTW, I noticed while experimenting with this that if I have an
environment of LANG="C", psql overrides the client_encoding to be
SQL_ASCII, regardless of what the database encoding is. This seems
like a bad idea, since it removes knowledge rather than adding any.
