available at SQL level taking some actions, however for the restart
the error handling is tricky if you just have control via psql. How
could you start a node that has been stopped during a restart but
could not boot up. Take the example of an incorrect parameter value
that has been added when the node was up via ALTER SYSTEM...
I was focused on admin task due to the pg_ctl (not sure you'd want to run that via psql...) but if you have shell script applications you want to run you could consider:
I used it a while back successfully but have since gone a more conventional route by embedding psql in shell and not the other way around.
