Well, maybe you've found an actual bug then; but without a test case
that other people can poke at, it's hard to investigate.

Older libpq versions should work fine with an 8.3 server --- if they
don't, that's a bug in itself.  I do not know the status of libpqxx
though; you might want to check whether there are known bugs in that
version.
