It looks like the final state of the regression tests doesn't include
any blobs before about 9.4. You wouldn't have seen any results worse
than a warning message in 7.4-8.4, unless there were some blobs so that
the data extraction loop got iterated.
It might be a good idea to retroactively modify 9.1-9.3 so that there
are some blobs in the final state, for purposes of testing pg_dump and
pg_upgrade.
