lwgeom_line_interpolate_point() LWGEOM * lwgeom_line_interpolate_point ( LWGEOM *  lwgeom, double  fraction, int32_t  srid, int  repeat  ) Get a geometry from a geography. Note PostGIS function: LWGEOM_line_interpolate_point(PG_FUNCTION_ARGS) Precondition fraction >= 0 && fraction <= 1 && lwgeom->type == LINETYPE
