Base de Dados corrompida

Recentimente redimencionei a partição que se encontrava a base de dados postgres.
porem quando copio ela devolta no novo postgres e tento acessa-la o seguinte erro aparece:

select * from fornecedor;
FATAL 2: XLogFlush: request is not satisfied
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.


como posso resolver isso???? <IMG SRC="images/forum/icons/icon27.gif">
