"What is the biggest integer the model field that this application instance can handle?"

We have sys.maxint, but I'm looking for the database+model instance. We have the IntegerField, the SmallIntegerField, the PositiveSmallIntegerField, and a couple of others beside. They could all vary between each other and each database type.

I found the "IntegerRangeField" custom field example here on stackoverflow. Might have to use that, and guess the lowest common denominator? Or rethink the design I suppose.

Is there an easy way to work out the biggest integer an IntegerField, or its variants, can cope with?
