version has nothing to do with it. You had to change pg_hba.conf - most
likely you changes "trust" authentication for local connections to
something like md5 or password.
it works exactly the same way in 8.2 as in 9.0 - if connection has
"trust" authenticator - password is not necessary.

best options are to either use .pgpass file (described here:
http://www.postgresql.org/docs/9.0/static/libpq-pgpass.html)
or setup system in such way that postgres user can login locally without
password, using ident authenticator. be warned though that ident, when
not well configured, is a common source of problems - described for
example here: http://www.depesz.com/index.php/2007/10/04/ident/
