Yes.  This will not be "fixed"; you'll have to adjust the view before
you can update it to v10.  (If you want those values, you should now
get them out of the pg_sequence catalog.)

This should have been called out as a significant incompatibility
in the v10 release notes, but I see that it's not listed in the
right section.  Will fix that ...
