/**
 * Returns the symmetric difference of two geometries, that is the parts of each geometry that are not shared by both. This is equivalent to the union of the two differences: `ST_UNION(ST_DIFFERENCE(geomA, geomB), ST_DIFFERENCE(geomB, geomA))`. Both geometries must share the same coordinate reference system.
 *
 * @example
 * ROW a = TO_GEOSHAPE("POLYGON ((0 0, 3 0, 3 3, 0 3, 0 0))"),
 *     b = TO_GEOSHAPE("POLYGON ((1 1, 4 1, 4 4, 1 4, 1 1))")
 * | EVAL symdiff = ST_SYMDIFFERENCE(a, b)
 * | KEEP symdiff
