PostgreSQL version: 9.1.4
Operating system: Red Hat
Description:

Hello.
I found a little bug in /etc/init.d/postgresql-9.x file (ok in 8.4 - since
9.x versions ?).
In my case, I've 5 databases on same server. Each database is start/stop
with this file 'service postgresql9.x start'.
Unfortunately, it uses only same file for status "pidfile:
/var/run/postmaster-9.2.pid".
In my case and with this configuration, I have only one file for all
databases.
So, I've modified this file on all servers :

1 - pidfile="/var/run/${NAME}.pid

2 - and case test :
....
case "$1" in
....
status)
status -p /var/run/postmaster-9.1.pid
by
status -p $pidfile

Thanks for all.
