To tell the truth, I delete the table using Windows PgAdmin. I guess it has
done the same operation, hasn't it?

It would be nice if pg_dump could backup the information from other tables,
not only showing failure message.

I agree. I ask people at #postgres for tools to check state of the DB, if
structure is
alive or corrupt, because in other cases I could only guess that something
is wrong when pg_dump fails. Would you like me to send you a copy of  data?
