Did anyone notice that this seems to be causing buildfarm member 'tern'
to fail the recovery check?  See here:

https://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=tern&dt=2017-04-21%2012%3A48%3A09&stg=recovery-check
which has
TRAP: FailedAssertion("!(lsn >= prev.lsn)", File: "walsender.c", Line: 3331)

Line 3331 was added by this commit.
