Both StartPoint() and EndPoint return NULL for me when I try to use them in
0.73. However, PointN() works just fine.
Try this and see what you get:
SELECT StartPoint(GeometryFromText('MULTILINESTRING((0 0,1 1))', 1));
startpoint
------------
(1 row)
SELECT PointN(GeometryFromText('MULTILINESTRING((0 0, 1 1))', 1), 0);
pointn
-----------------
SRID=1;POINT(0 0)
(1 row)
