it works on devel

[pavel@localhost pgsql]$ psql postgres
\psql (8.4devel)
Type "help" for help.

postgres=# create table foo(a int, b varchar);
CREATE TABLE
postgres=# insert into foo values(10, 'kuku'),(20,'aba');
INSERT 0 2
postgres=# select array(select row(a,b) from foo);        ?column?
--------------------------{"(10,kuku)","(20,aba)"}
(1 row)
