looking to have 7.x behavior on 8.2/8.3

If I invoke postgres with -d5 every interaction gets dumped to the screen.

example:

postgres(at)database:~$ psql template1
Welcome to psql 7.4.7, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit

template1=#

gets me this output:

How do I get that behavior on 8.2.x/8.3.x ?
