Problem with date calculation

Hi,

I'm a newbie to Postgresql and have a problem manipulating dates in a
function...

In fact, I want a function to add some days to the current date and return
the result date.

My code would be something like :

/***************************************************************************
*********/
CREATE OR REPLACE FUNCTION AddDay( int ) RETURNS timestamp AS '

DECLARE
_INTdays ALIAS FOR $1;

_DTcurrent timestamp;

BEGIN

_DTcurrent := NOW() + interval ''_INTdays days'';
RETURN _DTcurrent;

END'
LANGUAGE 'plpgsql';
/***************************************************************************
*********/

I know there is an error in the date calculation but don't know how to
calculate it....

Thanks for your help.
