Hi,
chipmunk (an armv6l-powered original Raspberry Pi model 1?) has failed
in a couple of weird ways recently on 14 and master.
On 14 I see what appears to be a corrupted log file name:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=chipmunk&dt=2022-06-16%2006%3A48%3A07
cp: cannot stat
\342\200\230/home/pgbfarm/buildroot/REL_14_STABLE/pgsql.build/src/test/recovery/tmp_check/t_002_archiving_primary_data/archives/000000010000000000000003\342\200\231:
No such file or directory
On master, you can ignore this failure, because it was addressed by 93759c66:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=chipmunk&dt=2022-05-11%2015%3A26%3A01
Then there's this one-off, that smells like WAL corruption:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=chipmunk&dt=2022-06-13%2015%3A12%3A44

manager data checksum in record at 0/79B4FE0
Hmmm. I suppose it's remotely possible that Linux/armv6l ext4 suffers
from concurrency bugs like Linux/sparc. In that particular kernel
bug's case it's zeroes, so I guess it'd be easier to speculate about
if the log message included the checksum when it fails like that...
