27837	After upgrade 1.4 to 1.8 in the database creats (or updates) mixed objects with old	Grigoriy Kramarenko	nobody	"Hello!
In start of January, I updated two completely different project from version 1.4.22 to version 1.8.16.
In these two highload projects began to appear mixed objects (periodically).
They include some data from other objects, plus the new data.
Despite the fact that the code is almost unchanged, except for the announcement of the transactions.
Moreover, I tried to catch this bug before saving to the database, but nothing showed.
I suspect the problem in an permanent database connection and in the new transaction with the repetition of old objects.
It is just not in psycopg2, because the return on Django 1.4 - resolves this issue completely.
Please tell me how to configure Django to the old behavior with a PostgreSQL database and resolve this problem for the future.
