Comment:
The problem is that Oracle does treat '' and None equivalently. And, this
shows in some places of Django.
The fix is likely incorrect as it doesn't check for
connection.features.interprets_empty_strings_as_nulls.
I am marking this as accepted. Haven't tested this but the description
seems correct.
