hard shutdown of system

["surabhi.ahuja" <surabhi.ahuja@xxxxxxxxxxx>]

the user tries to do kill -9 -1 and log in again

 

in the startup script i do the following

 

/sbin/pidof -s postmaster

 

and it still displays some value,

 

however ps -aef | grep postmaster does not display anything

 

is it ok if i do the following

 pid1=`/sbin/pidof -s postmaster`
 pid2=`ps -eaf | grep postmaster | grep -v grep | tail -1 | awk '{print $2}'`

if ($pid1 and $pid2)

=> postmaster is already running

 

otherwise

 

i check if postmaster.pid exists

if it does, i delete it

and then start postmaster by doing $PGCTL -l $POSTGRES_LOG -D $PGDATA -p $POSTMASTER -o '-p ${PGPORT}' start  > /dev/null 2>&1

 

is it ok?

 

thanks,

regards
