 * - PostGIS inflection (type names for subtypes, Z/M variants)
 * - Geometry field plugins (coordinates, GeoJSON output)
 * - Measurement fields (area, length, perimeter on geometry types)
 * - Transformation fields (centroid, bbox, numPoints on geometry types)
 * - Aggregate function definitions (ST_Extent, ST_Union, ST_Collect, ST_ConvexHull)
 * - Connection filter operators (26 spatial operators + withinDistance via declarative factory API)
 *
 * @example

 *   extends: [GraphilePostgisPreset]
 * };
