It's now up to three similar failures in the past ten days: in
addition to

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=habu&dt=2024-07-18%2003%3A08%3A08

I see

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=urutu&dt=2024-07-22%2018%3A00%3A46

And we have releases coming up fast.

(BTW, I don't think taipan qualifies as a slow machine.)
