Oh, so the row *is* there. What the above says is that you have a
corrupt index on attachment_id, which you should be able to fix via
REINDEX. However, I'm still a bit confused, because corrupt indexes
don't normally cause a problem for pg_dump (which is just doing SELECT *
or COPY, so the index wouldn't be consulted). Are the dumps you are
talking about perhaps made with something other than pg_dump?
