If you want to keep the same functions just do as follows
CREATE OR REPLACE FUNCTION nvl(TEXT,TEXT) RETURNS TEXT AS '
BEGIN
RETURN COALESCE($1,$2);
END;' LANGUAGE 'plpgsql';
You will have to do this for all supported data types unless you want to
put in a third parameter that would be the cast type
