I happened to have a virgin install of CentOS7 here, so I tried it on
that. I installed 9.2 and 10rc1 from repositories (CentOS and PGDG,
respectively) rather than from source, and repeated it and still got the
fast shutdown when hitting ctrl-C when 10rc1 has restarted the 9.2 server.

I did the initdb, start, and restart from pg_ctl, not from whatever
management tool comes with the packages. I did it both with the database
running as OS user jjanes, and separately running as OS user 'postgres', so
it doesn't seem to matter whether uid is high or low. And with '-l
logfile'.

So, I don't know.

Cheers,
