One point that was not mentioned is that while indexes are necessarily
tied to a single table, statistics objects might not always be. The
long-term hope is to allow statistics on cross-table combinations of
columns, which is why the syntax was intentionally set up to look like
SELECT. So, just like views, it's reasonable to give them independent
ownership.
