I'm trying to implement testing on a fairly large Django site, and I'm encountering a psycopg2 error when running all the tests at once using `python manage.py test`. If I specify each app name individually, it works fine (some tests fail, but all for legitimate reasons), however when I run them all at once, it works as expected for the first 20-30 tests, and then I get a large number failing at once, all with an interface error.

I've tried setting a really high value for CONN_MAX_AGE as well as leaving it as default (never close). I've looked at the test where it starts to fail (it's always the same one) and nothing appears out of the ordinary.
