Re: Weird failure with latches in curculio on v15 - Mailing list pgsql-hackers

My database off assertion failures has four like that, all 15 and master:

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=curculio&dt=2023-02-01%2001:05:17
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=curculio&dt=2023-01-11%2011:16:40

It's always in proc_exit() in StartupProcShutdownHandler(), a SIGTERM
handler which is allowed to call that while in_restore_command is
true.

Here's a different one, some kind of latch corruption in the WAL
writer under 017_shm:
