Absolutely. That's why you'd patch your startup/shutdown scripts. Adding it to
pg_ctl does enable those to kick the necessary stuff without requiring use of
the system's init scripts for manual control of the postmaster. When the
emphasis on the 'controlled' aspect of this is acknowledged then it's just a
toss up between editing pg_ctl or your own wrapper for it. I would go for my
own wrapper since then that still leaves the ability for pg_ctl to be used
_without_ kicking those startup/shutdown actions.
I believe this has arisen several times and each time there's been no
enthusiasm to stick cron into the core which I think is a reasonable stance.
