I've been known to back-patch stuff just to keep branches consistent,
but it's always a judgement call.  In this case I wouldn't have done it
(even if the patch were a good idea in HEAD) because it would cause
churn in translatable messages in the back branches.  Also, the case
for cosmetic back-patching is only strong when a particular file is
already pretty similar across all branches, and I'm not sure that
holds for pg_upgrade.
