Hi, I think there's some test instability:
Fail: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=parula&dt=2023-04-07%2018%3A43%3A02 Subsequent success, without relevant changes: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=parula&dt=2023-04-07%2020%3A22%3A01 Followed by a failure: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=parula&dt=2023-04-07%2020%3A31%3A02 Similar failures on other animals: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=komodoensis&dt=2023-04-07%2020%3A27%3A43 https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=siskin&dt=2023-04-07%2020%3A09%3A25 There's also as second type of failure: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=dragonet&dt=2023-04-07%2020%3A23%3A35 .. I suspect there's a naming conflict between tests in different groups. Greetings, Andres Freund
