other database backends, but the exception classes should still be the same.
This commit changes the way the tests check for specific database errors to be
more portable between implementations.
It's possible these tests will still fail if, e.g., Oracle doesn't raise
IntegrityError (but raises DatabaseError) when we except it to, but we can
cross that bridge if and when it appears.

This is a no-op for most databases. Only necessary on PostgreSQL so that we can
do things which will possibly intentionally raise an IntegrityError and not
have to rollback the entire transaction. Not supported for PostgreSQL versions
prior to 8.0, so should be used sparingly in internal Django code.

* Raise a ValueError if you try to assign the wrong type of object.
* Raise a ValueError if you try to assign None to a field not specified with null=True.
* Cache the set value at set time instead of just at lookup time.
This is a slightly backwards-incompatible change; see BackwardsIncompatibleChanges for more details.
