Hmm, I see.

Possibly, one way a user could recover from this is to add the column on
the subscriber, rename to table on the subscriber to the temp name, then
wait until all the changes from the rewrite are applied, at which point
it should start complaining in the logs that the original table name
does not exist, then rename the table back.
