7db4ab8439 [3.0.x] Fixed #31071 -- Disabled insert optimization for primary keys with defaults when loading fixtures. 
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.

0f8041abd5 [3.0.x] 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+.

implementation idea and review.

7b065c41e4 [3.0.x] 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.
