pg_upgrade would go through the same DDL path, so I expect it would be
set to -1 in the upgraded cluster anyway. Are you seeing something
different?

In any case, the change is just meant to improve consistency and
documentation. I didn't intend to create a hard guarantee that it would
always be -1, so perhaps I should make the documentation more vague
with "may be" instead of "is"?

It bothers me somewhat that views still have relpages=0, because they
also don't have storage. Thoughts?
