Check the appropriate user's permissions when enforcing rules about
letting a leaky operator see <structname>pg_statistic</structname>
data (Dean Rasheed)
</para>
<para>
When an underlying table is being accessed via a view, consider the
privileges of the view owner while deciding whether leaky operators
may be applied to the table's statistics data, rather than the
privileges of the user making the query. This makes the planner's
rules about what data is visible match up with the executor's,
avoiding unnecessarily-poor plans.
