1) restore from backup
2) fix whatever configuration you made to let windows (or your hardware) destroy your data on crash. is there some RAID cache that is not backed up by a battery?

IMHO If there's no hurry, it'd be better to start with point 2, because if your filesystem (or hardware) is somehow badly broken, it will happen again...
If you have more than one database in your cluster, you can find what's the database that's been corrupted and restore just that one, instead of the whole cluster.

Hello,

The computer had a unexpected shutdown, it is a Windows machine.

Now some data appears to be corrupted, I am receiving exceptions like this:

ERROR: could not read block 0 in file "base/16393/16485": read only

0 of 8192 bytes

There is some way to correct this?
