In a previous mail I stated something like "the name of the method doesn't matter"...... after better thinking I realized a decent name might be better than other ones...Let me say:
get_native_conn()get_native_connection()
might be better than "get_something_pgconn" because the same type of method could be useful for other databases in the future...More or less all the databases use a "native connection", only PostgreSQL uses "PGconn connection".
Have a good w.e.Ch.F.

I suppose it helps to debug the situation where the capsule is used
after the connection has been closed. Instead of a BOOM you get a nice
exception (if the consumer checks for it, obviously).
I'll work on this in my repo and if everything works we can integrate it
for 2.8.
