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?
