That's what I've done, so far so good, although we are still checking
consistency against the last backup.  Thanks for the info. Luckily this
was one of our smaller databases ...

I wish I knew - this is what appeared to start it:

Sep 24 10:19:41 snafu postgres[18176]: [464-1] ERROR:  could not open
segment 1 of relation "idx_ordl_id" (target block 1719234412): No such
file or
Sep 24 10:19:41 snafu postgres[18176]: [464-2]  directory

I can't figure out what the exact problem is; there were no I/O errors
or any other relative messages at the time, the box was empty, and
nothing remarkable was going on.  :(

thanks,
Cott

PS: No, I don't think it's a PG problem. :)
