Ok, this is much more difficult than I thought.

Turns out that there are at least two interfaces that expect an int not a long.

BatchUpdateException
executeBatch

I'm thinking the only option here is to report INT_MAX as opposed to failing.

Thoughts ?

I think we'll all be safely dead by the time anybody manages to process
2^63 rows in one PG command ;-).  If you can widen the value from int to
long on the Java side, that should be sufficient.
