The PR description states the postgres image is changed to ghcr.io/getsentry/image-mirror-library-postgres:14-alpine, but the Jinja template and the generated workflow files use 17-alpine. Pinning the CI postgres service to major version 17 rather than 14 is a larger version jump than documented and could surface unexpected compatibility issues in DB integration tests. Worth confirming the intended version and aligning the PR description with the code.
