Actually, on second look, I think this is expected behavior when trying to
update from pre-8.3 text search --- that whole conversion was none too
clean. Note the warning in the tsearch2 module documentation about
3. Load the dump data. There will be quite a few errors reported
due to failure to recreate the original tsearch2 objects. These
errors can be ignored, but this means you cannot restore the
dump in a single transaction (eg, you cannot use pg_restore's -1
switch).
If you weren't actually using the tsearch2 features before, you might be
best advised to uninstall tsearch2 from the old database before you
convert. If you were, please read the documentation about text search
conversion carefully --- both
http://www.postgresql.org/docs/8.4/static/textsearch-migration.html
and the contrib/tsearch2 page.
