Problemas con balanceo de carga

Hola,
Tengo montado PgCluster, he configurado dos nodos Cluster DB, un replicador y un balanceador de carga. He probado la réplica y lo hace muy bien al igual que la recuperación. Cuando intento conectarme al balanceador de carga con PgAdmin III, me devuelve el siguiente error:

"Error connecting to the server: server closed the connection unexpectedly. This probably means the server terminated abnormally before or while processing the request."

La configuración que tengo es como sigue:
cluster.conf en Cluster DB 1:

Agradecería cualquier ayuda, Gracias.
