There's a REINDEX command now that you can use in standalone mode
to recover from something like this.
The procedure is arcane (translation: I don't know it) so check
the documentation and follow it carefully.
I've fixed a few bugs in btree for 7.1 and am optimistically hoping
that this message will not be heard from again after 7.1 is out...
