Yes, I saw the failures: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=kestrel&dt=2022-04-28%2002%3A13%3A27 https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=rorqual&dt=2022-04-28%2002%3A14%3A08 https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=calliphoridae&dt=2022-04-28%2002%3A59%3A26 All of them are on 025_stuck_on_old_timeline.pl when the WAL receiver writes a TLI history file when fetching it from a primary, meaning that we need to think harder about this case as we would overwrite an existing TLI file once we use durable_rename() over durable_rename_excl(). I don't want to keep the buildfarm unstable, so I'll revert for now. -- Michael
