This is the PgBouncer log.

Actually, teardown_request should be executed for every single
interaction with the app (after every Ajax call for instance), so one
thing I tried (under the assumption that maybe the psycopg2 connection
should not be explicitly closed in such a PgBouncer-enabled setup) is
to simply comment it all out, but it didn't change the PgBouncer
behavior at all.
Also, according to this answer to the same question on dba.SE, it
seems that this log is
the expected behavior:
