Quick Varchar Question

Hi all,

    Just wondering if there is any way in Postgres 6.5 to force varchars
to be interpreted on an insert string as UPPER case only? ie: insert
into bla values ('lala') ....

    'lala' would be forced to uppercase WITHOUT using the upper()
function in the insert string.

    I need this because I'm shooting data in from applixware, and users
tend to type lower case.

Thanks, please reply to my email address
