Damn.. Sorry I missed that. Usually pg_ctl detaches from terminal.

When you start a job with nohup and put it in background, the job keeps running
even if terminal detaches.

When a terminal closes, a sighup is delivered to all applications started from
that terminal. Nohup just ignores it.

man nohup for more details.
