Is this a bug in 7.1?

Is this a bug or missing feature in 7.1? or have I got the SQL
wrong?

bray=# SELECT DISTINCT p.id, p.name, a.town
bray-#   FROM (
bray(#         SELECT id, name
bray(#           FROM customer
bray(#         UNION
bray(#         SELECT id, name
bray(#           FROM supplier
bray(#        ) AS p
bray-#        LEFT OUTER JOIN address AS a
bray-#          ON p.address = a.id
bray-#   WHERE p.id = '22002';
ERROR:  function applied to tuple is not supported for subSELECTs

What does the error message mean?  I can't see where a function
is involved.
