Postgres 8.3.7 -- EOF on client connection

Hi ,

      I installed postgres 8.3.7-1 in my windows machine. The server starts all right.However when i attempt a JDBC connection(Driver used: postgresql-8.3-604.jdbc4.jar), the following error is thrown:

2009-06-24 17:55:03.564 ISTERROR:  relation "befailover" does not exist
2009-06-24 17:55:03.564 ISTSTATEMENT:  SELECT HOSTADDRESS,RMIREGISTRYPORT FROM BEFAILOVER WHERE SERVERROLE='PRIMARY'
2009-06-24 17:55:03.580 ISTERROR:  relation "befailover" does not exist
2009-06-24 17:55:03.580 ISTSTATEMENT:  DELETE  FROM BEFAILOVER WHERE SERVERROLE='STANDBY'
2009-06-24 17:55:12.639 ISTLOG:  could not receive data from client: No connection could be made because the target machine
actively refused it.
2009-06-24 17:55:12.639 ISTLOG:  unexpected EOF on client connection

        I attempt the JDBC connection from the machine as the postgres server. There are no anti-virus server software or firewall involved. Can someone tell me what could be wrong with my setup.

Thanks.
