But I'd still like an explanation of why only about half of the population is showing a failure here. Seems like every machine should be seeing the LSN as moving backwards in this test. So (a) why aren't they all failing, and (b) should we change the test to make sure every platform sees that happening? regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
