📝 Walkthrough

The project now requires Python 3.11 or later. Source annotations, lint settings, pytest requirements, and CI Python-version matrices were updated to match the declared support range.

Changes: Python support and tooling modernisation

Layer / File(s)	Summary
Declare Python support and lint targets pyproject.toml, newsfragments/1440.feature.rst, newsfragments/1444.misc.rst	The project minimum and tooling targets are Python 3.11. Classifiers cover Python 3.11–3.15. Ruff enables the UP and PYI rulesets.
Update annotations and Python idioms pytest_postgresql/*, pytest_postgresql/executors/proc.py, pytest_postgresql/factories/*, pytest_postgresql/janitor.py, pytest_postgresql/loader.py, pytest_postgresql/retry.py, tests/*	Typing imports and annotations use current Python interfaces. The retry code and tests use datetime.UTC; the SQL loader omits the default read mode argument.
Align test matrices and oldest dependencies .github/workflows/*postgres*.yml, .github/workflows/tests.yml, .github/dependabot.yml, oldest/requirements.txt, newsfragments/+oldest-pytest.break.rst	CI matrices remove or raise selected Python versions. The oldest environment pins pytest 8.4.0, and its Dependabot entry ignores all pip dependencies.

Merge Risk: 🔵 Low · up to 5850f

The release note mentions dropping Python 3.10, but a separate breaking-change entry would make the compatibility change clearer. This is a limited release-communication risk; the other supplied changes align with the stated support range.

Full details: Linked Issues check

Explanation

Issue #1444 requires the UP and PYI Ruff rule groups and a mypy Python-version pin. pyproject.toml enables UP and PYI, sets Ruff and mypy to Python 3.11, and does not enable FA. The reported annotation and import updates implement the enabled rules. No separate test requirement appears in issue #1444.

Full details: Docstring Coverage

Explanation

Docstring coverage is 90.48% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 21 functions across 10 files. (10 skipped: 10 unsupported.)

Full details: Newsfragment Check

Explanation

The pull request adds three newsfragments: 1440.feature.rst, 1444.misc.rst, and +oldest-pytest.break.rst. All types are valid in the [tool.towncrier.type] configuration: feature, misc, and break.

Full details: Out of Scope Changes check

Explanation

The pull request contains changes not required by issue #1444 or the current description. These include Python 3.15 and Python 3.10 support changes in classifiers, CI matrices, and newsfragments/1440.feature.rst; a pytest downgrade in oldest/requirements.txt; and a Dependabot configuration that disables all pip updates. The related code modernisation and configuration changes support the Ruff and mypy objectives.

Resolution

Remove the unrelated support-policy, pytest-version, and Dependabot changes, or move them to separate pull requests with their own linked issues. Keep the UP/PYI configuration, mypy version pin, and changes required to satisfy those rules.
