📝 Walkthrough

Walkthrough

Python 3.15 is added to PostgreSQL CI matrices across reusable workflows and platform-specific jobs. Setup labels change from Pipenv to uv, while setup action wiring remains unchanged. The development psycopg-binary dependency is limited to CPython versions before 3.15, and a news fragment records the expanded CI coverage.

Changes

Python 3.15 CI coverage

Layer / File(s)	Summary
Expand PostgreSQL workflow matrices .github/workflows/single-postgres.yml, .github/workflows/oldest-postgres.yml, .github/workflows/dockerised-postgres.yml, .github/workflows/single-postgres-windows.yml, .github/workflows/tests.yml	Reusable workflow defaults and PostgreSQL job matrices add Python 3.15 across Linux, macOS, Docker, and Windows configurations.
Rename environment setup labels .github/workflows/single-postgres.yml, .github/workflows/oldest-postgres.yml, .github/workflows/dockerised-postgres.yml, .github/workflows/single-postgres-windows.yml	Python environment setup step labels change from Pipenv to uv while the referenced setup action remains unchanged.
Restrict the psycopg-binary development dependency pyproject.toml	psycopg-binary==3.3.4 is conditioned on CPython and Python versions earlier than 3.15.
Record Python 3.15 CI coverage newsfragments/+8a93a817.misc.rst	The news fragment states that Python 3.15 is included in CI.

In @.github/workflows/tests.yml:
- Line 151: Update the docker_postgresql_18 job configuration to pass a
python-versions list including Python 3.15, matching the existing PostgreSQL
14–17 Docker jobs, or update the shared Docker workflow default used when
python-versions is omitted. Ensure the PostgreSQL 18 matrix exercises Python
3.15 while preserving the existing versions.
- Line 132: Correct the malformed JSON value assigned to the Windows matrix
input python-versions by removing the extra quote before the 3.15 entry, while
preserving the existing Python version list so fromJSON can parse it
successfully.
