Hi,

Several animals are timing out while waiting for catchup,
sporadically. I don't know why. The oldest example I have found so
far by clicking around is:

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=skink&dt=2024-02-23%2015%3A44%3A35

So perhaps something was committed ~3 weeks ago triggered this.

There are many examples since, showing as recoveryCheck failures.
Apparently they are all on animals wrangled by Andres. Hmm. I think
some/all share a physical host, they seem to have quite high run time
variance, and they're using meson.
