+-- Test for overflow in array slicing
+CREATE temp table arroverflowtest (i int[]);

+INSERT INTO arroverflowtest(i[1:2147483647]) VALUES ('{}');

this example, master error is
ERROR:  source array too small
your patch error is
ERROR:  array size exceeds the maximum allowed (134217727)


INSERT INTO arroverflowtest(i[2147483647:2147483647]) VALUES ('{1}');
master:
ERROR: array lower bound is too large: 2147483647
you patch
ERROR:  array size exceeds the maximum allowed (134217727)

i think "INSERT INTO arroverflowtest(i[2147483647:2147483647]) VALUES ('{}');"
means to insert one element (size) to a customized lower/upper bounds.
