UNION and LIMIT issue

in pgsql 8.2 using LIMIT with UNION is throwing errors...

table is
-------------------------------

name quantity
character varying integer
-------------------------------
Banana 10
Cherry 10
Apple 5
Persimmon 3
Mango 2

the query :

SELECT name,quantity FROM fruit limit 3
UNION
select name,CAST(SUM(quantity) as integer) from (
select Cast('Other' as varchar) as name,quantity from fruit
limit ALL offset 3
) w group by name

throws an error on the UNION. Removing the first 'Limit 3' fixes the query,
but i need the limit statement. Anybody seen this behavior?
