Bugfixes
========
Fixed #31094 -- Included columns referenced by subqueries in GROUP BY on aggregations. Thanks Johannes Hoppe for the report. Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>

* Fixed a regression in Django 3.0 that didn't include columns referenced by a
``Subquery()`` in the ``GROUP BY`` clause (:ticket:`31094`).
Fixed #31109 -- Disabled grouping by aliases on QuerySet.exists(). Clearing the SELECT clause in Query.has_results was orphaning GROUP BY references to it. Thanks Thierry Bastian for the report and Baptiste Mispelon for the bisect. Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80.

* Fixed a regression in Django 3.0 where ``QuerySet.exists()`` crashed if a
queryset contained an aggregation over a ``Subquery()`` (:ticket:`31109`).
Fixed #31106 -- Fixed migrations crash on PostgreSQL 10+ when adding FK constraints inline and changing data. This allows adding foreign key constraints inline and changing data in the same migration on PostgreSQL 10+. Regression in 738faf9da2a5cd03148a36375db80746c99c9623. Thanks Janne Rönkkö for the report and Simon Charette for the implementation idea and review.
