Well, this host has a problem, for what looks like a kernel issue, I guess.. This is repeatable across all the branches, randomly, with various errors with the POSIX DSM implementation: # [63cf68b7.5e5a:1] ERROR: could not open shared memory segment "/PostgreSQL.543738922": No such file or directory # [63cf68b7.5e58:6] ERROR: could not open shared memory segment "/PostgreSQL.543738922": No such file or directory https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=tanager&dt=2023-01-24%2004%3A23%3A53 dynamic_shared_memory_type should be using posix in this case. Switching to mmap may help, perhaps.. I need to test it. Anyway, sorry for the noise on this one. -- Michael
