Another database recovery problem

My 7.2.1 database was in the middle of inserting a large object when the
power went down. When I restart the database I getting the following
messages:

postgres: startup subprocess : DEBUG sql sql sql DEBUG: database
system was interrupted at 2003-10-08 09:29:12 PDT
postgres: startup subprocess : DEBUG sql sql sql DEBUG: checkpoint
postgres: startup subprocess : DEBUG sql sql sql DEBUG: redo record
is at 0/115A3C; undo record is at 0/0; shutdown TRUE
postgres: startup subprocess : DEBUG sql sql sql DEBUG: next
transaction id: 95; next oid: 16557
postgres: startup subprocess : DEBUG sql sql sql DEBUG: database
system was not properly shut down; automatic recovery in progress
postgres: startup subprocess : DEBUG sql sql sql DEBUG: redo starts

postgres: startup subprocess : DEBUG sql sql sql DEBUG: ReadRecord:
record with zero length at 0/157F4C
postgres: startup subprocess : DEBUG sql sql sql DEBUG: redo done
at 0/157F28
postgres: startup subprocess : DEBUG sql sql sql DEBUG: database
system is ready


When I vacuum the database to remove used entries and to compact the db,
I get the following errors:

postgres: voicemail aesop 127.0.0.1 VACUUM: DEBUG sql sql sql DEBUG
--Relation pg_largeobject--
postgres: voicemail aesop 127.0.0.1 VACUUM: INFO sql sql sql NOTICE:

postmaster: DEBUG sql sql sql DEBUG: terminating any other active
server processes
postmaster: ERROR sql sql sql FATAL 1: The database system is in
recovery mode

and from then on any time we try to connect we get a message saying
database is in recovery mode and it never comes out. How can I recover
this database or do I have to restore a prior backup?
