Fixed #37075 -- Allowed overriding the PostgreSQL pool's "check" callable.

2026-04-30T23:52:11Z

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.

Refs #36005 -- Bumped minimum supported versions of 3rd-party packages.

This bumps minimum supported versions of 3rd-party packages to the first releases to support Python 3.12.

Fixed #35688 -- Restored timezone and role setters to be PostgreSQL DatabaseWrapper methods.

2024-08-28T22:25:07Z

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.

Refs #34200 -- Removed unnecessary check in DatabaseWrapper.ensure_role() on PostgreSQL.

2024-02-26T09:53:47Z

ensure_role() is only called in init_connection_state() where a new connection is established.

Simplified using DATABASES["OPTIONS"].

2024-02-23T06:49:43Z

DATABASES["OPTIONS"] are always configured.
