That's unfortunate

That seems the simplest approach. Both the 7.2 driver and server are
truely ancient now -- I think having to manually apply a patch if you
want to run against them isn't unreasonable.

That seems the most flexible approach, but reflection can be a pain to
deal with. For the packaging case, if you are going to build "PostGIS
for 7.2" and "PostGIS for 8.0" as separate packages then there doesn't
seem like much advantage to having a single PostGIS build/jar anyway.
