We didn't run into any issues here. close attention was paid to byte
ordering, the rest was handled by libpq's cross-platform handling.
cross-PG-version is a different story. the patch already uses server
version to toggle (like use int4 for money pre-8.3). If we make this a
separate library, it would be easy to plug in a newer or older one.
Merlin had some ideas here ... Merlin?
