  -h, --host=HOST     Host to bind to (default: 127.0.0.1)
  -u, --path=UNIX     Unix socket to bind to (default: undefined). Takes precedence over host:port
  -v, --debug=LEVEL   Debug level 0-5 (default: 0)
  -e, --extensions=LIST  Comma-separated list of extensions to load
                         Formats: vector, pgcrypto (built-in/contrib)
                                  @org/package/path:exportedName (npm package)
  -r, --run=COMMAND   Command to run after server starts
  --include-database-url  Include DATABASE_URL in subprocess environment
  --shutdown-timeout=MS   Timeout for graceful subprocess shutdown in ms (default: 5000)
