It might be cleaner to try and remove the tsearch bits from your
schema dump and get a fresh install of tsearch by itself before
loading in your own schema. Also, given you're making this leap, I'd
strongly encourage you to try and migrate to Postgres 9.2 instead of
8.4, which is the next version to be EOL'd. It's unlikely the pain
will be significantly worse than what you are going through now.
