Django and Postgres transaction rollback

I have a piece of code that works in a background process which looks like ``` from django.db import transaction try: <some code> transaction.commit() except Exception, e: print e transaction.rollback() ``` In a test, I break `<some_code>` with data that causes a database error. The exception is following ``` File "/home/commando/Development/Diploma/streaminatr/stream/testcases/feeds.py", line 261, in testInterrupt form.save(self.user1) File "/usr/lib/pymodules/python2.5/django/db/transaction.py", line 223, in _autocommit return func(*args, **kw) File "/home/commando/Development/Diploma/streaminatr/stream/forms.py", line 99, in save print(models.FeedChannel.objects.all()) File "/usr/lib/pymodules/python2.5/django/db/models/query.py", line 68, in `__repr__ ` data = list(self[:REPR_OUTPUT_SIZE + 1]) File "/usr/lib/pymodules/python2.5/django/db/models/query.py", line 83, in `__len__ ` self._result_cache.extend(list(self._iter)) File "/usr/lib/pymodules/python2.5/django/db/models/query.py", line 238, in iterator for row in self.query.results_iter(): File "/usr/lib/pymodules/python2.5/django/db/models/sql/query.py", line 287, in results_iter for rows in self.execute_sql(MULTI): File "/usr/lib/pymodules/python2.5/django/db/models/sql/query.py", line 2369, in execute_sql cursor.execute(sql, params) InternalError: current transaction is aborted, commands ignored until end of transaction block ``` This is what I expect. The bad thing is that I still get the same error when I try to access the DB after `transaction.rollback` is called. What should I do to rollback the transaction succcessfully and make the connection usable once again? Btw, I also tried inserting `print connection.queries` to debug the code, and it always returns an empty list. Could it be that Django is using some other DB connection? The code is run outside of request-response cycle. I tried switching TransactionMiddleware on and off, but it gave no effect. I am using Django 1.1 and Postgres 8.4.
