(1) PostgreSQL does not support dump and restore from a new version
of PostgreSQL to an older version.

(2) There were changes to UTF8 handling between 8.1 and 8.2. I'm a
bit surprised you get an error like this as 8.1 is more lax than 8.2:
it accepts some invalid sequences as valid.

If you're really determined to do this, I recommend editing the dump
file by hand to remove or edit this record so it does not contain the
invalid sequence (as you've suggested).
