Hi all,

Bacula catalog in Postgress has become corrupted it seems due to disk errors.
I can still make a backup, but cannot dump the catalog anymore.

It does write most of the catalog, but doesn't complete.

This occurs after a lot of full backups this weekend, so I am not fond of 
deleting the catalog and reloading the one from friday.

The catalog resides on an ordinary IDE disk.

Does anyone have a suggestion as to how I can best rescue the system - how can 
I get the full catalog copied over to a new disk and continue to run?

I have been thinking of simply restarting the server, then it would repair the 
disk structure if possible, but how can I best prepare for the scenario that 
it won't and can't start or that the repair will destroy the catalog?
