It is mention as a bug with a workaround in the ticket 660
http://typo.leetsoft.com/trac/ticket/660
my own workaround is go back to a previous version, to rename the file
db/migrate/36_relate_contents_and_page_caches.rb to
db/migrate/36_relate_contents_and_page_caches.rb.old before the svn
update to 849, then update to version 849, revert the name to
db/migrate/36_relate_contents_and_page_caches.rb and do the update on
admin page... it works for me!
or you can do the change in the database as mentioned in the ticket
regards.
