Reported and proposed patch by: Hirotaka Igarashi

In a case defining postgres-8 resource under ip resource and this ip-address has net-mask, postgres-8.sh does not generate appropriate configuration file.

Example configuration:
<ip address="10.3.1.10/24 monitor_link="1"">
      <postgres-8 name="db_svr"/>
</ip>

From this kind of cluster.conf, postgres-8.sh generates postgresql.conf as follows,
----------------------
listen_addresses = '10.3.1.10/24'
----------------------
 
it causes postmaster's unsuccessful startup.

        for i in $ip_addressess; do
                # modified by hiro so that it supports netmask
                i=`echo $i|sed -e 's/\/.*$//'`
                if [ $x -eq 1 ]; then
                        x=0
                        ip_comma=$i
