Fwd: Re: pg_dump error

Hi,

Already doing Vacuum analize procedure on daily basis.
But the pg_dump fails on ONLY one table.
That table works normal for other operations. But we
are feeling uncomfortable to keep using that table as
unable to backup.

Can anyone give a hint how to fix the pg_dump issue

Thanks

Manjula
