I've added another patch, 0003, to resolve this wrap-around. In fact I
discovered a bug that the following statement is accepted and inserts
an empty array into the table.
INSERT INTO t(ia[-2147483648:2147483647]) VALUES ('{}');
My patch resolves this bug as well.
The other patches, 0001 and 0002, are unchanged but have their version
number incremented.
As a reminder, 0001 is reviewed and waiting for v18 and a committer.
0002 and 0003 are unreviewed. So, I'm going to mark this as waiting for
a reviewer.
Thanks,
Joe Koshakow
