Обсуждение: pgsql: Fix handling of auto-updatable views on inherited tables.

Fix handling of auto-updatable views on inherited tables.

An INSERT into such a view should work just like an INSERT into its base
table, ie the insertion should go directly into that table ... not be
duplicated into each child table, as was happening before, per bug #8275
from Rushabh Lathia.  On the other hand, the current behavior for
UPDATE/DELETE seems reasonable: the update/delete traverses the child
tables, or not, depending on whether the view specifies ONLY or not.
Add some regression tests covering this area.
