BaseDatabaseSchemaEditor._iter_column_sql().

2021-07-02Refs #26430 -- Re-introduced empty aggregation optimization.Simon Charette
The introduction of the Expression.empty_aggregate_value interface allows the compilation stage to enable the EmptyResultSet optimization if all the aggregates expressions implement it. This also removes unnecessary RegrCount/Count.convert_value() methods. Disabling the empty result set aggregation optimization when it wasn't appropriate prevented None returned for a Count aggregation value. Thanks Nick Pope for the review.
2021-07-02Fixed #26430 -- Fixed coalesced aggregation of empty result sets.Simon Charette
Disable the EmptyResultSet optimization when performing aggregation as it might interfere with coalescence.
2021-07-01Fixed #32893 -- Fixed serialization of models.Model class in migrations.abhiabhi94
Migrations assumed that an import of the models.Model class must already be included when it's serialized, but for models with only custom fields this was not necessarily the case. Thanks Jaap Joris Vens for the report.
