2026-04-30Fixed #37075 -- Allowed overriding the PostgreSQL pool's "check" callable.HEADmaininitial-branchRaoni Timo
Setting "check" in OPTIONS["pool"] previously raised TypeError because the PostgreSQL backend always passed check= to ConnectionPool() and unpacked **pool_options on top, regardless of CONN_HEALTH_CHECKS. The user's callable now takes precedence via setdefault(); pool_options is copied first to avoid mutating the user's settings dict.

2025-12-31Refs #33647 -- Fixed silent data truncation in bulk_create on Postgres.Simon Charette
Regression in a16eedcf9c69d8a11d94cac1811018c5b996d491. The UNNEST strategy is affected by the same problem bulk_update has wrt/ to silent data truncation due to its usage of db_type which always returns a parametrized subtype.
2025-12-26Fixed #36112 -- Added fallback in last_executed_query() on Oracle and ↵VIZZARD-X
PostgreSQL.
2025-12-22Fixed #36818 -- Ensured SQLite connection before accessing max_query_params.guro-Ishiguro
Regression in 358fd21c47cdf7bda520ce73c5cfd82bba57827b.
2025-12-05Fixed #36722 -- Moved AutoFieldMixin validate_autopk_value() check to ↵Clifford Gama
get_db_prep_save. The validation in validate_autopk_value is specific to saving. Having it in get_db_prep_value caused Value(0, AutoField()) to fail unexpectedly when used in a filter on MySQL. Thanks Jacob Walls for the review.

Thanks to Jacob Walls for the report and previous iterations of this fix, to Simon Charette for the logging formatter idea, and to Tim Graham for testing and ensuring that 3rd party backends remain compatible. This partially reverts d8f093908c504ae0dbc39d3f5231f7d7920dde37. Refs #36112, #35448. Co-authored-by: Jacob Walls <jacobtylerwalls@gmail.com>

2025-02-16Refs #35967 -- Deprecated BaseDatabaseCreation.create_test_db(serialize).Simon Charette
Given there are no longer any internal usages of serialize=True and it poses a risk to non-test databases integrity it seems appropriate to deprecate it.
2025-02-09Fixed #36105 -- Dropped support for MariaDB 10.5.Mariusz Felisiak
2025-02-01Fixed #36088 -- Avoided unnecessary DEFAULT usage on bulk_create().Simon Charette
When all values of a field with a db_default are DatabaseDefault, which is the case most of the time, there is no point in specifying explicit DEFAULT for all INSERT VALUES as that's what the database will do anyway if not specified. In the case of PostgreSQL doing so can even be harmful as it prevents the usage of the UNNEST strategy and in the case of Oracle, which doesn't support the usage of the DEFAULT keyword, it unnecessarily requires providing literal db defaults. Thanks Lily Foote for the review.

2024-12-16Refs #29850 -- Removed obsolete test_window_frame_raise_not_supported_error.Tim Graham
This NotSupportedError was removed in 6375cee490725969b4f67b3c988ef01350c1ad6d because it will never be reached due to the same exception raised by Window.as_sql().
2024-12-11Fixed #35936 -- Used unnest for bulk inserts on Postgres when possible.Simon Charette
This should make bulk_create significantly faster on Postgres when provided only literal values. Thanks James Sewell for writing about this technique, Tom Forbes for validating the performance benefits, David Sanders and Mariusz Felisiak for the review.
2024-08-28Fixed #35688 -- Restored timezone and role setters to be PostgreSQL ↵Sarah Boyce
DatabaseWrapper methods. Following the addition of PostgreSQL connection pool support in Refs #33497, the methods for configuring the database role and timezone were moved to module-level functions. This change prevented subclasses of DatabaseWrapper from overriding these methods as needed, for example, when creating wrappers for other PostgreSQL-based backends. Thank you Christian Hardenberg for the report and to Florian Apolloner and Natalia Bidart for the review. Regression in fad334e1a9b54ea1acb8cce02a25934c5acfe99f.
