WAL Crash during index vacuuming 7.1beta4

during the nightly vacuum pgsql closed and do not start any more.
Attached the log.

Seems the problem was rebuilding an Index,
There is a way to force wal to ignore indexes ?

The problem was in redoing tuple movement in *table*.

Can I delete it ?

...

DEBUG: redo starts at (6, 4144414796)
NOTICE: PageAddItem: tried overwrite of used ItemId

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

FATAL 2: heap_update_redo: failed to add tuple

I think that I've just fixed this problem (must not check itemid'
flag in PageAddItem in overwrite mode when offset number
== maxoff + 1). I hope that Giuseppe will check new code soon.

Thanks to Giuseppe for help!
