Subject: Is there an upper limit on the size of an array if it is indexed?

I have created a unique index on an array of integers, and it works for a
small test case:
create table i(id int not null primary key,
v int[] not null unique );
insert into i(id, v) values(1, ARRAY[1,2]);
-- fails
insert into i(id, v) values(2, ARRAY[1,2]);
-- succeeds
insert into i(id, v) values(2, ARRAY[2,1]);
Is there an upper limit on the size of an array being indexed? I am
currently considering arrays of 2K-3K integers.
