I've already downgraded / dumped the databases and upgraded to the
latest version. I was then going to create the new databases however I
can't connect because of the invalid data error:

I guess I'm just missing something here...I didn't choose to go with
the 'pg_upgrade' script simply because I wasn't aware of it's location
and was worried it would dork up my data so I reverted back to 8.4.4-6
and got a clean backup of my databases. So is there nothing I can do
from my position now?
