"pg_ctl stop/restart" checked that the postmaster PID is valid just
once, as a side-effect of sending the stop signal, and then would
wait-till-timeout for the postmaster.pid file to go away. This
neglects the case wherein the postmaster dies uncleanly after we
signal it. Similarly, once "pg_ctl promote" has sent the signal,
it'd wait for the corresponding on-disk state change to occur
even if the postmaster dies.
I'm not sure how we've managed not to notice this problem, but it
seems to explain slow execution of the 017_shm.pl test script on AIX
