Not really. It waits for up to 60 seconds and if the shutdown was not
successful (as there was a connected client), it prints a message to the log

pg_ctl: server does not shut down
HINT: The "-m fast" option immediately disconnects sessions
rather than

and returns 1.

If you really need to wait for shutdown, you need to add "-w" to the
command line, use "-m fast" or "-m immediate".

But even ignoring the return value should not cause corruption IMHO.
