error:varchar too long - how to get details?

Hi everyone !

I've got a little question :-)

When I try to insert too long string into some varchar(n) column,i get a
message like this:
ERROR:value too long for type character varying(10)

It's ok - but how can I get information,which column generates an error?
Is it possible ?

I don't see any hint or detail message(in psql) ,like in other cases (at
example, when i try to call
non existing function)...

Postgres version: 8.1

Best regards and thanks for help,
Kacper Chrapa
