It also happens with Ubuntu 22.10 (Kernel 5.19.0-23-generic). We now try 
6.0 mainline and 5.15. mainline kernel on some servers.

I also forgot to mention that /var/lib/postgresql/12 directory is 
encrypted with fscrypt (ext4 encryption). So we also deactivated the 
directory encryption on one server to see if it is related to 
encryption.
