date style bug

obelix3=> set datestyle=postgres,euro;

obelix3=> select * from orden_visita where fecha_emision <= 'today'::date;
ERROR: Bad date external representation '07-17-2001'

Since '07-17-2001' is *not* a valid date in Euro convention
(dd-mm-yyyy), I don't see any bug here.

I take it fecha_emision is a text or varchar field that your query is
casting to date on-the-fly. Perhaps you'd be better advised to use
datatype date (or timestamp) for the field in the first place.

I'm having this bug ramdonly, some time with a "vacuum analyze" goes
away but not always

Likely not related at all.

obelix3=> set datestyle=postgres,us;
SET VARIABLE
obelix3=> select * from orden_visita where fecha_emision <= 'today'::date;
numero | corredor | ejecutivo | remoto | cliente | retira | tipo_operac
ion | fecha_emision
--------+----------+-----------+-----------+-----------+-----------+------------
----+---------------
292 | 78626380 | 6607775 | 127.0.0.1 | 8779524 | 8779524 |
Venta
QUERY RUNS OK.

What is the value of the fecha_emision column? What is the schema?

obelix3=> set datestyle=postgres,euro;
obelix3=> select * from orden_visita where fecha_emision <= 'today'::date;
ERROR: Bad date external representation '07-17-2001'

What is the schema? I'll guess that fecha_emision is not actually a date
type (either date or timestamp) but rather a text field. That is the
only way I can think of to provoke an "external representation" error.

More details please.

Here is it:
-------------

obelix3=> \d orden_visita
                                 Table "orden_visita"
   Attribute    |  Type   |                         Modifier                          
----------------+---------+-----------------------------------------------------------
 numero         | integer | not null default nextval('orden_visita_numero_seq'::text)
 corredor       | integer | not null
 ejecutivo      | integer | not null
 remoto         | inet    | not null
 cliente        | integer | not null
 retira         | integer | not null
 tipo_operacion | text    | not null default 'Arriendo'
 fecha_emision  | date    | default date("timestamp"('now'::text))
Index: orden_visita_pkey
