The docs state that postmaster.pid is "A lock file recording the
current postmaster PID and shared memory segment ID (not present after
postmaster shutdown"
I never looked until now, but I see the number 5432001 where the pid
should be, and the real pid is in /tmp/.s.PGSQL.5432.lock, along with
the path to data.
Is the documentation incomplete/misleading or am I doing something odd?
