Eh? That sounds wonky.
I mean, reboot normally kills processes with SIGTERM or SIGKILL, in
which case I'd expect the outcome to match what you get with pg_ctl
stop -mf or pg_ctl stop -mi. The only way I can see that you'd get a
different behavior is if you did a hard reboot (like echo b >
/proc/sysrq-trigger); if that changes things, then we might have a
missing-fsync bug. How is that reboot managing to leave the main fork
behind while losing the init fork?
