enable_geospatial_use_geodesic (bool)

• Default value (as of this release): True

This configuration parameter controls the geodesic behavior of the h3_coverage function used in geography join acceleration.

• If true: Use exact geodesic computation, where arcs between coordinates follow the curved surface of the Earth.
• If false: Use a simplified interpolated computation, where curves are approximated by a sequence of straight segments.

Use this setting to balance geometric accuracy with performance, depending on the precision requirements of your spatial workload.
