Oh, of course: the reason the test doesn't fail as given on 9.2 is that
9.2 doesn't have a lock_timeout parameter. (I missed the complaints about
this in the blizzard of other noise the test generates :-(.) The timeout
is critical to exposing the bug because it needs failed lock acquisitions.
Probably unpatched 9.2 would fall over if you used statement_timeout
instead.
