Comment (by Simon Charette):
For the record I tried the above and
[https://github.com/django/django/pull/19285 proposed a patch] for #27222
that [https://github.com/django/django/pull/19298 can be built upon to
support] for `update(returning)` in a backward compatible way by using the
following signature discussed on the mailing list
{{{#!python
# Existing signature with keyword only updates.
@overload
def update(self, **updates) -> int: ...
# New signature with positional only updates to preserve backward
# compatibility with update(updates={"something"}) for models with
# an "updates" field.
@overload
def update(self, updates: dict, /) -> int: ...
# New signature with positional only updates and returning support which
# also allows paves the way for other options in the future if needs be.
@overload
def update(
self, updates: dict, *, returning: list[str] | tuple[str]
) -> list[tuple]: ...
}}}
It supports SQLite, PostgreSQL, and Oracle.
