My problem is that I can't even start postmaster to perform the
reindex on now. As soon as I try start (via pg_ctl, 8.1.10):
postgres_report[24165]: [1-1] LOG: database system was interrupted
while in recovery at 2007-10-04 12:32:46 NZST
postgres_report[24165]: [1-2] HINT: This probably means that some
data is corrupted and you will have to use the last backup for
recovery.
