KusuDB: Operational Error occurred when connecting to the DB

I have RHEL5.3 that is with the Platform Cluster Manger PCM installation. on master node. Unfortunately some files were deleted from the /var directory and then the postgresql service couldn't start. I have deleted, rm -rf /var/lib/pgsql/data and started the service again now the service is running but I cannot run some administrative commands including cluster tasks (which are very important).

for example
Code:
[root@pmd02 ~]# addhost
KusuDB: Operational Error occurred when connecting to the DB
       Most likely cause: insufficient permissions for user=nobody
FATAL:  Ident authentication failed for user "nobody"

ERROR:  Database query failed!  Make sure the database is available


How can I get rid of this error. I cannot afford reinstallation of PCM as many applications are running on the master node.

NAME
crm_uuid - get a node's UUID SYNOPSIS
crm_uuid [-w|-r] DESCRIPTION
UUIDs are used to identify cluster nodes to ensure that they can always be uniquely identified. The crm_uuid command displays and modifies the UUID of the node on which it is run. When Heartbeat is first started on a node, it creates a UUID (in binary form) in /var/lib/heartbeat/hb_uuid. This file can be read and written by means of crm_uuid. Note There are very rare circumstances when crm_uuid should be used to modify the UUID file. The most common is when it is necessary to set a node's UUID to a known value when creating a new cluster. OPTIONS
--write, -w Write a UUID value to the /var/lib/heartbeat/hb_uuid file. Warning Use the -w option with care, because it creates a new UUID value for the node on which it is run. Various scripts across the cluster might still use the old value, causing the cluster to fail because the node is no longer associated with the old UUID value. Do not change the UUID unless you changed all references to it as well. --read, -r Read the UUID value and print it to stdout. SEE ALSO
/var/lib/heartbeat/hb_uuid AUTHOR
