OK, I have applied this mega-patch.  It applied cleanly, except for the
documentation changes.  This is because I restructured the order of the
functions recently.  I manually added your doc changes.

As this includes all your previous patches, my guess is that we are all
caught up with you now in the CVS tree for 7.2.

As far as changes, 7.2 would be fine for changing the API, if there is a
good reason to do it.  For example, I see getLength returns a short. 
With 7.1's new longer tuples, that should now be changed to int, at
least.  (I have updated libpq++/TODO to mention this.)

Not sure what else you have in mind, but you are in pretty much total
control of the C++ library if you want to improve it.

Thanks for the patches.
