Thanks, for the fix, now the function works, but unfortunately it's a

PyCapsule https://docs.python.org/2/c-api/capsule.html, suggested by
Federico seems a more viable approach:

If Psycopg was able to retrieve a PyCapsule, XTA should be able to use
it and the Python interpreter would be a gateway between two C/C++
distinct modules (Psycopg and XTA).
I'm going to perform some experiments in the XTA wrapper before coming
back to this mail thread.
If you want the capsule, just pull from my report:
https://github.com/fogzot/psycopg2/tree/feature-expose-pgconn
and use the feature-expose-pgconn branch.

Everything will be OK at the end. If it's not OK, it's not the end.
