Thanks a lot Tom, I appended the -h /tmp and it worked. I need just one more help from you. Could you tell me that why & how that socket file existed in /tmp directory. What is the practice to make sure that this file (.s.PGSQL.5432) should be inside /var/run directory ? so that it will not throw such error. Please help me.
