Viewing new 9.3 error fields

This blog entry displays the new 9.3 error fields, schema/table/constraint:
http://www.depesz.com/2013/03/07/waiting-for-9-3-provide-database-object-names-as-separate-fields-in-error-messages/$ INSERT INTO t (i) VALUES (1);psql:z.sql:16: ERROR:  23505: duplicate key value violates unique constraint "t2_pkey"DETAIL:  Key (i)=(1) already exists.CONTEXT:  SQL statement "INSERT INTO t2 (i) VALUES (NEW.i)"PL/pgSQL function copy_value() line 4 at SQL statement
-->	SCHEMA NAME:  public
-->	TABLE NAME:  t2
-->	CONSTRAINT NAME:  t2_pkeyLOCATION:  _bt_check_unique, nbtinsert.c:398

However, I am unable to see this in psql:
CREATE TABLE ledger (id SERIAL, balance NUMERIC(10,2) unique);SET log_error_verbosity = 'verbose';INSERT INTO ledger VALUES (DEFAULT, 1);INSERT INTO ledger VALUES (DEFAULT, 1);ERROR:  duplicate key value violates unique constraint "ledger_balance_key"DETAIL:  Key (balance)=(1.00) already exists.

What am I missing?
