hi,
yah i took this script only and built upon that
the problem is that the statement
"pidof postmaster"
will return some valu even if
ps -aef | grep postmaster does not return anything
if i do kill -9 <process id of postmaster?
and i do pidof postmaster,
some machines it will show nothing
and on some machines it still shows some value, althou ps -aef | grep postmaster does not display anything.
so in such machines i ll have to check for both, pidof as well as ps -aef | grep postmaster.
is this ok?

Check out the startup script. Depending on what system you are
running, this might already all be taken care of.
Here's a mandrake example (I think the redhat version is pretty similar).
