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.

and MySQL. Also removed tests that ensured that adapt_(date)timefield backend operations where able to deal with expressions when it's not the case for any other adapt methods.
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.
