Sorry, that might be confusing. That 10:43 is the time when script
renames and copies the logfiles (not the waldump)

I meant to show the name of the waldump file:

waldump.20170309_1021_1039.1.5.000000010000002700000069.txt.bz2
where:

20170309_1021 is the start-time of the script
1 is master (2 is replica)
5 is wait-state cycles during which all 8 md5s remained the same
1039 is the time, 10:43, just before the pg_waldump call
