So it seems we're just doing too many connections and too many queries. Each page view from a user translates to multiple requests to the application server and each of those translates to a connection and at least a few queries (which are done in middleware and therefore happen for each and every query). One pgbouncer can handle lots of concurrent idle connections and lots of queries/second but our 9000 queries/second to seem push it too much. The longer term solution for us would probably be to do less connections (by doing less Django requests for a page) and less queries, before our deadline we were just searching for a short term solution to handle an expected traffic spike.
The typical solution to that is caching, see https://docs.djangoproject.com/en/1.4/topics/cache/.
