Bug report: OIDs, roles and Windows (signedness issue?)

Hi

On Windows, if a user role's OID exceeds 256^4/2 - 1 (aka 2147483647),
the OID is displayed as 2147483647 and additional information for that object
(e.g. ACL information) is not displayed.

We have verified this happens with pgAdmin3 1.16.0 on Windows 7 and
1.18.1 on Windows 2012 server. It does not happen on Linux (1.16.1), where
the OID (FWIW, it's 3794942497) for the role in question displays correctly as
well as the ACL information.

Please let me know if you need any more details.

Regards

Ian Barwick
