Yes, it's a pg connection object. Both pg and pgdb resort to the same 
underlying _pg module actually providing these connection objects.

No, this is an undocumented feature. Actually it is a private attribute, 
so it seems D'Arcy wanted to discourage using it, probably because mixed 
use of both interfaces may lead to problems. The official way would be 
to open a separate connection using the pg module.

However, I don't see a problem using the inserttable method that way.
Should we consider a semi-official method of accessing the underlying 
_pg connection or even taking over all or some of its methods to the 
pgdb connection? D'Arcy, what do you think?
