Re: major database breakdown

Hi Tom,

I did delete everything from pg_statistic. It helped somewhat but
still there is something strange. Please see the transcript of my 
session below. How can I fix these broken indexes? I can't drop and 
recreate them.

Would be nice to get back online.

Thanks

Ulrich
