Surprising, but not new (probably has been there back to the Berkley
code), and has come up before on one of the lists (I think it might even
have been pgsql-bugs).

regression=# select version();
version
------------------------------------------------------------------------
PostgreSQL 7.3.5 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2
20030222 (Red Hat Linux 3.2.2-5)
(1 row)

regression=# create table foo (a int[]);
CREATE TABLE
regression=# insert into foo values (null);
INSERT 1104092 1
regression=# update foo set a[3] = '42';
UPDATE 1
regression=# select a, a is null from foo;
a | ?column?
---+----------
| t
(1 row)

I'm still hoping to scrounge up the time to continue working on arrays
for 7.5, including figuring out how to deal with this.
