Hmmm ... I wonder whether this is related to the known problem that
8.3's pg_dump doesn't correctly detect file seekability under Windows:

That means the dump file will not contain any data offset pointers.
Up to now that was only known to cause issues for parallel pg_restore,
but maybe you found another case. But that's just a hypothesis, and a
quick test here doesn't seem to support it: I can still do pg_restore -a
from a blob-containing dump that I forced to not have data offsets.
OTOH I'm not using Windows.

Does it work any better if you use 9.0's pg_dump to dump from the 8.3
server?
