Seems, error messages are too inconsistent. If you forbid omitting bound in
assigment then if all cases error message should be the same or close.
Done.  Skipping lower boundary is no longer an error.

Thank you for your review.

Much better, but:

# create table xxx (a int[]);
# update xxx set a[2:] = '{1,2}';
UPDATE 0
# insert into xxx values ('{1,2,3,3,4,4,5}');
INSERT 0 1
# update xxx set a[2:] = '{1,2}';
ERROR:  cannot determine upper index for empty array

As I understand, update should fail with any array, so, first update should fail too. Am I right?
