Yesterday, I was attempting to reload a remote copy of a postgresql database that had been corrupted. Creating the new db went well, as did reloading the data schema, but somewhere during the reload of the data itself, I lost the remote connection. After killing the now-unworking putty connection and opening a new one, I discovered that neither the postgresql system, nor the postmaster it uses, were running. And when I try to restart the postmaster, I get the following page of errors:

LOG: database system was interrupted while in recovery at 2007-07-31 08:54:40 CDT
HINT: This probably means that some data is corrupted and you will have to use the last backup for recovery.

I googled for the panic message and found a small thread on the postgresql hacker's mailing list detailing a similar event, but the thread gave no clues as to how to resolve the issue. Can anyone here think of anything that might help solve this problem?
