How to turn off output generated by psql

I guess this could be viewed as the equivalent to oracles "set" statements in sqlplus, for example "set heading off verify off feedback off echo off":

proddb01=# \dn
           List of schemas
           Name           |  Owner
--------------------------+----------
 sales                    | postgres
 hr                       | postgres
 manufacturing            | postgres
 public                   | postgres
 (4 rows)

Turn off unneccessary output like this:

proddb01=# \t
Tuples only is on.

Try again:

proddb01=# \dn
 sales                    | postgres
 hr                       | postgres
 manufacturing            | postgres
 public                   | postgres
