upper() and lower() on varchar

Hi,

Is there a way to get upper() and lower() to work on a varchar column? It
seems like these functions are only defined on the text datatype (in 6.3.2).

I guess what I need in this case is some way to convert varchar to text.
Will (text_in(varchar_out(column)) work?

Maarten
