36675	Oracle dialect depends on implementation detail which was changed in python-oracledb 3.4	Anthony Tuininga	Varun Kasyap Pentamaraju	"This issue was reported by a Django user with the upgrade to python-oracledb 3.4: https://github.com/oracle/python-oracledb/issues/544. The issue is that the Django Oracle dialect depended on an implementation detail which changed in python-oracledb 3.4.

The following patch addresses that and is fine for all supported versions of cx_Oracle and python-oracledb:
