Were you *really* on 8.3 before?  Because that function hasn't existed
since 8.2.

You need to follow the procedure for updating pre-8.3 tsearch2
installations, as described in the manual:
http://www.postgresql.org/docs/8.4/static/textsearch-migration.html
(I believe BTW that some errors of the sort you show above are expected
while doing this process.  If that's what you're doing, just ignore it.)

Alternatively, if you weren't actually doing anything with the
contrib/tsearch2 functions, you could just uninstall them from the older
database and then repeat the dump.
