Comment (by cjerdonek):
I also ran into this issue with Django 1.9.7.
What I observed is that with `CONN_MAX_AGE=None`, after
`LiveServerTestCase.tearDownClass()`, querying PostgreSQL's
`pg_stat_activity` shows a lingering connection in state "idle" (which was
a connection created by the test case).
It looks like the culprit may be Django's
[https://github.com/django/django/blob/418658f453bed7fe7949dda26651aab370003e6a/django/test/testcases.py#L1230
LiveServerThread]. The idle connections are not closed when the thread
terminates. It looks like that's what the most recent patch proposes.
Other info:
PostgreSQL 9.3.13, psycopg2 2.6.2, Python 3.5.2.
