Short Description
Trouble with timestamps after vacuuming

Long Description
I had a table in which one field is a timestamp:
CREATE TABLE blabla (
[...]
"update_time" timestamp with time zone
[...]
)

I did a pg_dump of the table and then i wanted to re create it and it gives me the following error:

Query failed: ERROR: Bad timestamp external representation '06/05/2002 11:42:10 ART'

I had to take out the " ART" part (sed s/" ART"/""/ did the trick)
But if i do a pg_dump again, the same happens, so i can't have a backup ready-to-go.
Is it a bug? a feature? or some setting somewhere?

PostgreSQL 7.2.3 on i586-pc-linux-gnu, compiled by GCC 2.96 (redhat 7.2, postgres installed from sources)

Thanks,
Marcelo.

Sample Code
INSERT INTO "indices" ("ind_nombre","cierre_ant","precio_ult","update_time") VALUES ('MERVAL','525.0900','524.9500','02/01/2003 11:08:02 ART');
