Can anybody recall a reason for why the do_restart() function in pg_ctl
copies a lot of code almost right off from do_stop(), instead of just
having that code exactly the same as do_stop() and factored out? (Like
it does for do_start() already)
I see the point in dealing with the very first branch differently, but
for example why do we do the postmaster_is_alive() patch only in
restart and not in stop?
