seems like your ps is not standards redhat. "ps -u postgres" works
fine for me on RH60 and RH61. This could easily affect the way your
init script works - the functions us ps in part to get pid values.
I'd run the stop repeatedly until you always get a 'failed' trying to
stop the db. Then run the start.
I've got a suspician that inittab may not ne synced and init is still
restarting the postmaster on you. I'm not sure, but it may be worth
double or triple checking.
Good luck
