Re: postgresql service started but pid is not saved in /var/run/postgresql/postgresql.pid

Hey,

I'm using a machine in aws and when the machine starts all the services are starting including postgresql(v9.6 , centos).  However, when I check the service`s status I see that it is stopped but all the processes are up (ps -ef ) and the postmaster.pid file is exist with the pid of the postmaster. 

The next part of code responsible for starting postgresql in redhat(/etc/init.d/postgresql) :

It seems that the sleep 2 isnt enough time to start the processes and thats why the service shows that the instance is down while it is up. Does any one faced this type of issue ? I mean, I can increase the sleep , but I dont think that it is the perfect solution in this case.
