Handle untype-cast string as VARCHAR instead of TEXT

Hi all

I'm dealing with a system where string values is queried but not necessary
type-cast.
E.g.
SELECT case when some_value=1 then 'some string' else 'another string' end
FROM some_table;
This will return a column cast as type TEXT;

Is there some configuration option (or hack?) available which will return
above as VARCHAR ?

I'm using 3rd party software where a VARCHAR value displays much better than
TEXT.
I know best practice will be to type-cast , but I'm hoping for a quick-fix
here :)

Regards
