The test is trying to verify the application name reported by the
"remote" session, which isn't constant, so we can't just do "select
application_name from pg_stat_activity". I agree that terminating the
connection seems like kind of a strange thing to do --- maybe it's to
ensure that we get a new session with the updated application name
for the next test case? If not, maybe we could do "select 1 from
pg_stat_activity where application_name = computed-pattern", but that
has the same problem that a cache flush might have terminated the
remote session.
