To recap:
- your app only does inserts
- there has been no rollback lately
- there are no updates
- there are no deletes
The only other source of dead rows I can think is triggers ... do you
have any? (Not necessarily on this table -- perhaps triggers on other
tables can cause updates on this one).
Oh, rolled back COPY can cause dead rows too.
