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.

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.
2026-03-19Fixed #36795 -- Enforced quoting of all database object names.Simon Charette
This ensures all database identifiers are quoted independently of their orign and most importantly that user provided aliases through annotate() and alias() which paves the way for dropping the allow list of characters such aliases can contain. This will require adjustments to raw SQL interfaces such as RawSQL that might make reference to ORM managed annotations as these will now be quoted. The `SQLCompiler.quote_name_unless_alias` method is kept for now as an alias for the newly introduced `.quote_name` method but will be duly deprecated in a follow up commit.
2026-03-12Fixed #36727 -- Deprecated Field.get_placeholder in favor of ↵Simon Charette
get_placeholder_sql. The lack of ability of the get_placeholder call chain to return SQL and parameters separated so they can be mogrified by the backend at execution time forced implementations to dangerously interpolate potentially user controlled values. The get_placeholder_sql name was chosen due to its proximity to the previous method, but other options such as Field.as_sql were considered but ultimately rejected due to its different input signature compared to Expression.as_sql that might have lead to confusion. There is a lot of overlap between what Field.get_db_prep_value and get_placeholder_sql do but folding the latter in the former would require changing its return signature to return expression which is a way more invasive change than what is proposed here. Given we always call get_db_prep_value it might still be an avenue worth exploring in the future to offer a publicly documented interface to allow field to take an active part in the compilation chain. Thanks Jacob for the review.

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.

2025-12-16Fixed #36800 -- Restored ManyToManyField renaming in ↵Clifford Gama
BaseDatabaseSchemaEditor.alter_field(). Regression in f9a44cc0fac653f8e0c2ab1cdfb12b2cc5c63fc2. Now that ManyToManyField is no longer concrete the decision of whether or not it should be altered, which is also relied on by field renaming, should take into consideration name changes even if it doesn't have a column associated with it, as auto-created many-to-many relationship table names are a base of it. Note that there is room for optimization here where a rename can be entirely avoided if ManyToManyField.db_table remains stable between .name changes, just like we do with Field.db_column remaining stable, but since this is a regression and meant to be backported the current patch focuses on correctness over further improvements. Thanks Josik for the report. Co-authored-by: Simon Charette <charette.s@gmail.com>
