Try libpqxx; the development versions have had large object support for
months now.  The only reason I haven't bumped that feature to stable yet
is that I don't have any test cases for mixed-mode access yet (ie.,
mixing read and write objects to the same large object).

It offers two interface levels for large objects: as standard C++ I/O
streams or as more C-style "write n bytes" or "write this std::string"
operations on handle objects.  Either should suit you, although you'd
want to be careful to disable whitespace skipping and such on I/O streams.

Find it at http://pqxx.tk/
