What's online about this restart? Just that the tcp port keeps listening? I assume all running transaction will have to be aborted, right? And connections dropped?

The postmaster is effectively your supervisor. It could see the child segfault and abort the whole DB, but that would be deferring supervision to your init system. Not ideal.
