Testing this with an array with non-default lower bounds, it fails to
preserve the array bounds, which I think it should (note:
array_reverse() and array_shuffle() do preserve the bounds):
SELECT array_reverse(a), array_shuffle(a), array_sort(a)
FROM (VALUES ('[10:12][20:21]={{1,2},{10,20},{3,4}}'::int[])) v(a);
-[ RECORD 1 ]-+-------------------------------------
array_reverse | [10:12][20:21]={{3,4},{10,20},{1,2}}
array_shuffle | [10:12][20:21]={{10,20},{3,4},{1,2}}
array_sort | [1:3][20:21]={{1,2},{3,4},{10,20}}
