54 * Obtain a geometry/geography point from the GSERIALIZED WITHOUT creating
55 * the corresponding LWGEOM. These functions constitute a **SERIOUS**
56 * break of encapsulation but it is the only way to achieve reasonable
57 * performance when manipulating mobility data.
58 * The datum_* functions suppose that the GSERIALIZED has been already
59 * detoasted. This is typically the case when the datum is within a Temporal*
60 * that has been already detoasted with PG_GETARG_TEMPORAL*
61 * The first variant (e.g. datum_point2d) is slower than the second (e.g.
62 * datum_point2d_p) since the point is passed by value and thus the bytes
63 * are copied. The second version is declared const because you aren't allowed
64 * to modify the values, only read them.
