Django's postgres_psycopg2 adapter sets the connection's isolation level to psycopg2.extensions.ISOLATION_LEVEL_READ_COMMITTED when autocommit == False.
My application requires a more strict isolation level, so I am forced to create a new backend and override DatabaseWrapper._set_isolation_level to make sure the connection has the correct isolation level set.
There should be a configuration option within the database config in settings.py that allows users to set the appropriate isolation level if the default level is not correct for their application. It would also be nice if there was an option to not set the isolation level at all, and instead rely on the default isolation level provided by the Postgres server.
