How about: make sure you have enough free space because the table
will effectively double in size? Assuming it hasn't already been
updated a few times without vacuuming :).

It is safe to assume that postgresql will still handle the out of
disk space scenario gracefully - no data corruption - the transaction
fails and that's it?
