Array with a lower bound>1, PostgreSQL 8.3.6

Hello List,

I was wondering if there are any plans to properly support arrays with a
lower bound greater than one:

CREATE TABLE test ( a TEXT[]);
INSERT INTO test values ('[100:100]={}');

SELECT * FROM test;
       a
---------------
 [100:100]={1}


SELECT a[100],a[10] IS NULL FROM test;

Intuitively I'd expect result columns to behave in a similar
way, with the result array looking like:

[None  for x in xrange(99) ].append(1)

while currently [1] is returned.

    Regards,
            Thomas
