That's one way.  Another way would be for the function to use OUT
parameters (if you're running 8.1) or to return a custom type so
you could omit the column definition list.  Then the query would be:

SELECT *
FROM sp_frontalerts_summary(1, '2006-07-27 18:08:09', '2006-07-27 19:58:15');

The function and how you're calling it look correct except that
count() returns bigint, not int.  You didn't mention what error
you're getting but I'd guess it's "wrong record type supplied in
RETURN NEXT".  Try using "numitems bigint" instead of "numitems int".
