Re: Runtime error: could not open segment 1 of relation ...

Thanks for the suggestion ...no evidence of such a shutdown. The first of these errors (since 2005-10-28) was at 2006-09-26 05:37:19.157 PDT today; machine was last shut serveral weeks ago. There's been several large updates since then (sort of batch process for updates, then the server is read-only for 99.999 of the time).

Hi Greg,

Is it possible that the server was shutdown using -mi switch?

cuz immediate shutdown ends causing these problems.
