PostgreSQL - Base de datos borrada

Buenas a todos,

el problema es el siguiente: Tenemos una aplicación con una base de datos postgresql 8.2. con Windows. En el momento en que según el log se produjo el fallo, se hizo una conexión remota al servidor, con un sistema de control remoto, se desistaló tomcat, se volvio a instalar una nueva versión y se bajo y subió el servicio de postgres.

El caso es que la carpeta donde se encontraba el tablespace de la base de datos desapareció.

Lo que aparece en el log es lo siguiente:

Alguien sabe que ha podido pasar y como podemos recuperarlo.
