Hi everyone,
I want ot seek your help identifying the expected behaviour in the scenario when we hit `
systemctl reboot` command. When we run above mentioned command, PostgreSQL immediately closes the connections and shuts down without following the order mentioned in the service unit file. Since PostgreSQL is not waiting
for dependent services to shut down first, services are crashing if they are trying to access PostgreSQL at that time. I further debugged it in the system journal file and found that systemd logs out the control group user of postgres immediately. I have these two questions around it.
1. Why does PostgreSQL not wait for other dependent services to stop at the time of reboot?
2. What is the role of the control group user, and why does systemd log it out at the time of reboot immediately?
Thanks in advance, and looking forward to hearing from you.
