This update introduces `PG_DSN_CANDIDATES` for specifying multiple DSN options, improving compatibility and CI portability. The script now attempts connections sequentially using the provided candidates before falling back to single DSN or raising an error. Relevant updates to documentation and workflow configuration have also been made.
Introduced a GitHub Actions workflow to verify compatibility with PostgreSQL versions 14 through 18. Implemented a smoke test script to check core database metrics and version-specific differences. Updated the README with details about the compatibility matrix and usage instructions for the script.
Replaced `localhost` references with `<SERVER_IP>` or custom domain options. This clarifies instructions for setting up the application on a remote server.
Replaced German text with English across the frontend UI for consistency and accessibility. Enhanced clarity in `.env.example` and `README.md`, adding detailed comments for environment variables and prerequisites. Improved documentation for setup, security, and troubleshooting.
