Problem with pg_convert from 8.4 -> 9.0

 Uh, is there a way around this problem?

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.....

I belive you are incorrect.  They are in the public schema so I am not
sure how they are "system".  They are prefixed with "pg_" but that
should not be a problem.

Usually I tell folks to dump/delete/reload those tables and use
pg_upgrade for everything else, as the error message suggests.

That appears to be working.... not sure why it didn't before....

Actually you should be able to just drop and forget those tables.
They appear to be carry-forwards from a pre-8.3 installation of
contrib/tsearch2.  If so, they don't do anything useful anymore.
(Read the manual's section about migrating from pre-8.3 tsearch.)

Possibly you tried to remove the similarly-named system catalogs
(in pg_catalog)?
