Fixed #31071 -- Disabled insert optimization for primary keys with defaults when loading fixtures.

2019-12-30T06:49:10Z

Model.save_base() is called directly when loading fixtures and assumes existing rows will be updated. Branching of "raw" allows to maintain the optimization introduced in #29260 while supporting this edge case. Regression in 85458e94e38c20e57939947ee515a1a53689659f. Thanks Reupen Shah for the report.

Fixed #31106 -- Fixed migrations crash on PostgreSQL 10+ when adding FK constraints inline and changing data.

2019-12-23T22:28:59Z

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.

Fixed #31109 -- Disabled grouping by aliases on QuerySet.exists().

2019-12-23T08:24:03Z

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 #31094 -- Included columns referenced by subqueries in GROUP BY on aggregations.
