Thanks for the feedback, Harald.

How about specifying different aliases to the resulting values?
This will be handy when I use the same function multiple times in the same
query. 
(the function will take another input parameters used in the calculations)

E.g.:
SELECT itemid, (calcvalues(itemid, '2011-06-06')).*, (calcvalues(itemid,
'2011-06-07')).* FROM itemlist;
itemid | calcval1 | calcval2 | calcval1 | calcval2
--------+----------+----------+----------+----------      4 | 0.67     | 10.00    | 0.64     | 65.23      5 | 1.55
|45.00    | 1.23     | 23.25      6 | 3.60     | 69.00    | 2.98     | 62.66 
 
How will I manage unique column names for this output?
