This blog entry displays the new 9.3 error fields, schema/table/constraint:

INSERTINTO t (i) VALUES (1);psql:z.sql:16: ERROR:  23505: duplicate key value violates unique constraint

-->    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?
