2026-06-03Fixed #36492 -- Restored exact boolean lookup against literals on SQLite.Simon Charette
Performance regression in 37e6c5b on SQLite. Just like MySQL, and presumably Oracle, which don't have a native boolean type and incidently store booleans in integer columns, indices on such columns cannot be used when explicit boolean literal equalities are omitted. Adapt the logic introduced by refs #32691 for MySQL to be used for all backends that don't support native boolean fields instead of special casing MySQL, SQLite, and Oracle in their own special way. Note that review of this work surfaced that SQLite's query planner also cannot make use of indices when dealing with expressions of form WHERE NOT (indexed_bool_field = false) but that's a long standing problem unrelated to the restorative work performed in this patch. Thanks Klaas van Schelven for the report.
2026-03-19Refs #36795 -- Removed unnecessary prohibits_dollar_signs_in_column_aliases ↵Simon Charette
feature flag. Now that user provided aliases are systematically quoted there is no need to disallow the usage of the dollar sign on Postgres.

2025-04-30Refs #36052, #32234 -- Removed create_test_table_with_composite_primary_key ↵Simon Charette
flag in favor of using CompositePrimaryKey. Now that Django properly supports creating models with composite primary keys, the tests should use a `CompositePrimaryKey` field instead of a feature flag to inline backend specific SQL for creating a composite PK. Specifcially, the inspectdb's test_composite_primary_key was adjusted to use schema editor instead of per-backend raw SQL.
2025-03-03Fixed #35444 -- Added generic support for Aggregate.order_by.Chris Muthig
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.
