LINESTRINGM(1 0 1,2 0 2,4 0 4)
Oh, I get it. And there is a native way in postgis to calibrate the line
from a given set of measured points instead of using the ends?

If I understand it correctly I could:
1) mylinestringm = ST_AddMeasure(mylinestring, measure_start, measure_end);
2) Add the given set of points to mylinestringm with ST_AddPoint
3) Using ST_SetPoint to move the original vertexes.
Is that correct? I'm very interested to know if there is a more direct
and proper way to create a route from a set of points.
ST_MakeLine [1] can be used to aggregate a sequence of points into a line.
