[orm] [bug] [regression] Fixed regression caused by #7861 where invoking an
Insert construct which contained ORM entities directly via
_orm.Session.execute() would fail.
[postgresql] [bug] Scaled back a fix made for #6581 where "executemany values" mode
for psycopg2 were disabled for all "ON CONFLICT" styles of INSERT, to
not apply to the "ON CONFLICT DO NOTHING" clause, which does not include
any parameters and is safe for "executemany values" mode. "ON CONFLICT
DO UPDATE" is still blocked from "executemany values" as there may
be additional parameters in the DO UPDATE clause that cannot be batched
(which is the original issue fixed by #6581).
[orm] [usecase] Added _orm.with_polymorphic.adapt_on_names to the
_orm.with_polymorphic() function, which allows a polymorphic load
(typically with concrete mapping) to be stated against an alternative
selectable that will adapt to the original mapped selectable on column
names alone.
[orm] [usecase] Added new attributes UpdateBase.returning_column_descriptions and
UpdateBase.entity_description to allow for inspection of ORM
attributes and entities that are installed as part of an Insert,
Update, or Delete construct. The
Select.column_descriptions accessor is also now implemented for
Core-only selectables.
