Re: Some questions about the array.

Some inconsistency (if we believe that omitted lower bound is equal to 1):
regression=# insert into arrtest_s values 
('[-1:9]={3,1,4,1,5,9,5,6,7,8,9}'::int[], null);
INSERT 0 1
regression=# UPDATE arrtest_s SET a[:2] = '{23, 24, 25}';
ERROR:  source array too small
regression=# UPDATE arrtest_s SET a[1:2] = '{23, 24, 25}';
UPDATE 1

Seems, omitting boundaries in insert/update isn't a good idea. I suggest to 
allow omitting only in select subscripting.
