Thank you for reviewing the patch so quickly.  You are right, I don't think 
get_pgpid() here is no longer necessary.  If the pid changes in one second, 
i.e. the original postgres terminates and "pg_ctl start" starts another one, 
"pg_ctl stop" can terminate successfully because the original postgres it 
was waiting for actually terminated.

I'll submit the revised patch tomorrow.
