2025-01-20[5.2.x] Fixed #36107 -- Adjusted UNNEST bulk_create strategy to opt-out ↵Simon Charette
sized arrays. The array fields opt-out heuristic failed to account for sized arrays. Note that we keep relying on db_type as opposed to performing an ArrayField instance check against the column's field as there could be other implementations of model fields that use Postgres arrays to store the optimization must be disabled for all of them. Refs #35936. Thanks Claude Paroz for the report and test. Backport of 22fc151bb86a553d84c62d7effd289356e9b6c6c from main.
2024-12-17Fixed #35969 -- Disallowed specifying a USING clause for altered generated ↵lufafajoshua
field. PostgreSQL versions 16.5 and above no longer permit the use of a USING clause when changing the type of a generated column.
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.

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.

True on PostgreSQL." This reverts commit 9cf9c796be8dd53bc3b11355ff39d65c81d7be6d due to a crash on Oracle as it didn't allow multiple indexes on the same field.

2024-01-12Fixed #35028 -- Disabled server-side bindings for named cursors on psycopg >= 3.Simon Charette
While we provide a `cursor_factory` based on the value of the `server_side_bindings` option to `psycopg.Connection` it is ignored by the `cursor` method when `name` is specified for `QuerySet.iterator()` usage and it causes the usage of `psycopg.ServerCursor` which performs server-side bindings. Since the ORM doesn't generates SQL that is suitable for server-side bindings when dealing with parametrized expressions a specialized cursor must be used to allow server-side cursors to be used with client-side bindings. Thanks Richard Ebeling for the report. Thanks Florian Apolloner and Daniele Varrazzo for reviews.

2023-05-10Fixed #34553 -- Fixed improper % escaping of literal in constraints.Simon Charette
Proper escaping of % in string literals used when defining constaints was attempted (a8b3f96f6) by overriding quote_value of Postgres and Oracle schema editor. The same approach was used when adding support for constraints to the MySQL/MariaDB backend (1fc2c70). Later on it was discovered that this approach was not appropriate and that a preferable one was to pass params=None when executing the constraint creation DDL to avoid any form of interpolation in the first place (42e8cf47). When the second patch was applied the corrective of the first were not removed which caused % literals to be unnecessary doubled. This flew under the radar because the existings test were crafted in a way that consecutive %% didn't catch regressions. This commit introduces an extra test for __exact lookups which highlights more adequately % doubling problems but also adjust a previous __endswith test to cover % doubling problems (%\% -> %%\%%). Thanks Thomas Kolar for the report. Refs #32369, #30408, #30593.
