Problem with pg_convert from 8.4 -> 9.0

 Uh, is there a way around this problem?

$ bin/pg_upgrade -c -d /usr/local/pgsql-8.4/data -D data -b
/usr/local/pgsql-8.4/bin -B bin

These two databases use the full-text "Tsearch2" module.....  I can't
remove these tables either; they're marked "system" and even as a
superuser removing them is not permitted.

Does this mean that I have to dump and restore, and can't use convert?
If so that's a real bummer.....
