jacana didn't like it:

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=jacana&dt=2021-09-29%2018%3A25%3A53

The relevant info seems to be

# Running: pg_basebackup -D /home/pgrunner/bf/root/REL_14_STABLE/pgsql.build/src/test/recovery/tmp_check/t_026_overwrite_contrecord_primary2_data/backup/backup -h 127.0.0.1 -p 59502 --checkpoint fast --no-sync
pg_basebackup: error: connection to server at "127.0.0.1", port 59502 failed: FATAL: no pg_hba.conf entry for replication connection from host "127.0.0.1", user "pgrunner", no encryption
Bail out! system pg_basebackup failed

which looks like a pretty straightforward bogus-connection-configuration
problem, except why wouldn't other BF members show it?
