/**
 * PostgisTransformationFieldsPlugin
 *
 * Adds transformation fields to PostGIS geometry/geography object types:
 *
 * - `centroid`: The geometric centroid of the geometry (client-side calculation)
 * - `bbox`: The bounding box of the geometry as [minX, minY, maxX, maxY]
 * - `numPoints`: Number of coordinate points in the geometry
 *
 * These are client-side transformations computed from GeoJSON coordinates.
 * For server-side PostGIS transformations (ST_Transform, ST_Buffer, ST_Simplify,
 * ST_MakeValid), use SQL computed columns or custom mutations.
 *
 * Note: ST_Transform, ST_Buffer, ST_Simplify, and ST_MakeValid take parameters
 * (target SRID, buffer distance, simplification tolerance) that make them better
 * suited as custom SQL functions or mutation fields rather than static object fields.
