Help!! Crash recovery

I know you've probably discussed this in many places, but I have a crash
right now I need to recover from, and I'm not finding documentation that
fast.
Where should I go?

Here are the details on starting, after a kill -9 of a process brought
Postgres down.

Is there a page/s with information on quick recovery after corruption?
LOG: could not create IPv6 socket: Address family not supported by protocol
LOG: database system was interrupted while in recovery at 2007-04-05
08:18:47 EDT
HINT: This probably means that some data is corrupted and you will have
to use the last backup for recovery.
