Ok but why not you just cast since the input data is compatible anyway,
at least from what I saw up there...
sj$ psql -efq --no-psqlrc
begin;
BEGIN
create temp table foo as
select '08/06/2014 03:08:58'::text as ts;
SELECT 1
Table "pg_temp_7.foo"
Column | Type | Modifiers
--------+------+-----------
ts | text |
select ts::timestamptz
from foo;
ts

2014-08-06 03:08:58-05
