Note that 8.1 was EOL'ed on Windows specifically even earlier than it
was in general.

A workaround could be to run pg_restore on a 64-bit Unix box, talking
to postgresql server on Windows. That should work around the issue -
since the bug is in pg_dump/pg_restore and not in the backend.

But I second and thid Heikkis recommendation that you need to get off
version 8.1 and onto something more recent as quickly as possible.
