PQsetNoticeReceiver issues

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'm writing a onion-skin thick wrapper around the libpq library in Python.
This is my way of getting back into C and also getting a lot more
familiar with PostgreSQL.

I've run into a conundrum with the PQsetNoticeReceiver function call. How
do you set it back to the original default? How do you call the
appropriate PQnoticeProcessor as well?

I expected to find a function in the library like PQdefaultNoticeReceiver,
but either I'm looking at the wrong file or it doesn't exist. I also
expected to see PQdefaultNoticeProcessor, but nothing turned up. While
the documentation contains a neat implementation of a default
PQnoticeProcessor, it doesn't seem to be defined in the library.

Another issue that I am running into is that while the documentation
claims that PQnoticeReceivers may call PQnoticeProcessors, it doesn't
mention how this is to be done. How do I find out which PQnoticeProcessor
is connected to a PGresult?

I though that I could perhaps access it directly by including libpq-int.h,
but that seems to be missing from 7.4 now. (Should the note about not
using libpq-int.h in the documentation be removed now that it isn't there
anymore?)
