libpqxx and large objects

The latest versions of libpqxx offer a preliminary Large Objects
interface that lets you slot a large object into a standard C++
istream, iostream or ostream with all the features that entails.

If anyone is interested in advanced large objects usage, please take
a look and tell me:
- If it works, and what you do with it.  I'd like to hear about it   either way.
- What test cases I could add to my regression test.  One thing I  haven't tested yet is mixed read/write access.
- What I could change in the interface.  I know I still need to  build my own stream classes around the streambuf
class,so that  part of the interface is going to get a lot cleaner.
 

Please, if you have some time, download the 1.6.1 source tree from the
Developer branch on http://pqxx.tk/ and let me know!


TIA,
