FATAL 2 : after a vacuum, can't start postmaster anymore

Hi,

After doing a vacuumdb my postmaster went down due to diskspace
problems. At first I gained 650 Mb then all of it was retaken.

Messages from the serverlog:

DEBUG: starting up
DEBUG: database system was interrupted being in recovery at 2001-04-27
21:43:53 This propably means that some data blocks are corrupted
and you will have to use last backup for recovery.
DEBUG: CheckPoint record at (1, 2148175408)
DEBUG: Redo record at (1, 2146413588); Undo record at (1, 1692823116);
Shutdown FALSE
DEBUG: NextTransactionId: 2358581; NextOid: 4569236
DEBUG: database system was not properly shut down; automatic recovery
in progress...
DEBUG: redo starts at (1, 2146413588)
NOTICE: PageAddItem: tried overwrite of used ItemId
FATAL 2: heap_update_redo: failed to add tuple
Startup failed - abort

How to get things in the air again ?
