The field value will wrap around to -2^31 and then climb to 0 again.
At that point, you get duplicate values (if the field definition
allows it).

No, about 2 * 10^10.

If that estimate was based on the assumption that the integer limit is
2 * 10^30, you'll run out of numbers in 3,1536 nanoseconds :-)

But if you don't expect the number of rows to ever exceed 2 milliard
(Am.: billion), then an integer field is just fine.
