PANIC: failed to re-find parent key in "100924" for split pages 1606/1673

Hi All,

I have a database that refuses to start due to the afformentioned error. I am running POstgreSQL 8.1.11 on a Debian Etch box.

Does anyone know what this error means and how to recover from it?

Any help will be very much appreciated.

Thanks,
Val

P.S. Here is the complete output I get
