Ensured that rel_obj_attr and instance_attr return matching (pk, cls) tuples
in GenericForeignKey.get_prefetch_queryset(), preventing mismatches when
prefetching related objects where pk and get_prep_value() differ. Using
value_to_string() also makes this code compatible with composite primary keys.
Previously, the ADMINS and MANAGERS settings were lists of (name, address)
tuples (where the name had been unused). Deprecated use of tuples.
Updated settings value sanity checks, and changed from ValueError to
ImproperlyConfigured.
- Separated MailTests.test_connection_arg test cases.
- Expanded test cases for incorrect values of ADMINS/MANAGERS settings.
- Added test case verifying correct values of ADMINS/MANAGERS settings.
Thank you Adam Johnson for the report and fix. Thank you Sarah Boyce for
your spot on analysis.

partially reverted in this branch.

Raising DatabaseError directly made it harder than it should to
differentiate between IntegrityError when a forced update resulted in no
affected rows.
Introducing a specialized exception allows for callers to more easily
silence, log, or turn them update failures into user facing exceptions
(e.g. 404s).
Thanks Mariusz for the review.

This moves the behaviors of `order_by` used in Postgres aggregates into
the `Aggregate` class. This allows for creating aggregate functions that
support this behavior across all database engines. This is shown by
moving the `StringAgg` class into the shared `aggregates` module and
adding support for all databases. The Postgres `StringAgg` class is now
a thin wrapper on the new shared `StringAgg` class.
Thank you Simon Charette for the review.
This allows the proper resolving of F("field__transform") when
performing constraint validation.
Thanks Tom Hall for the report and Sarah for the test.
Given there are no longer any internal usages of serialize=True and it
poses a risk to non-test databases integrity it seems appropriate to
deprecate it.
While the top-level objects fed to serialization are bound to the test
database being created nothing prevents code invoked during
serialization from performing queries against other connections entries
that haven't been swapped yet.
The reported example of that is a database router directing all reads to
a test mirror for a set of models involving auto-created many-to-many
fields. It might be tempting to address the many-to-many field case but
this a symptom of a larger problem where the test framework yields the
flow execution to user code that could interact with non-test databases
in unexpected ways.
Deferring test database fixture serialization until the point where all
connections entries have been swapped for their test equivalent ensures
that no code triggered during serialization can interact with non-test
databases.
Thanks Jake Howard for the report and Jacob Walls for the initial
investigation.
When Expression.__init__() overrides make use of *args, **kwargs
captures their argument values are respectively bound as a tuple and
dict instances. These composite values might themselves contain values
that require special identity treatments such as Concat(output_field)
as it's a Field instance.
Refs #30628 which introduced bound Field differentiation but lacked
argument captures handling.
Thanks erchenstein for the report.
