ST_StartPoint - not works correctly

[sanyasi]

In the Quantum, I draw a point, and the line emerging from it.

1)

select ST_x(ST_StartPoint(geo)),ST_y(ST_StartPoint(geo)),ST_StartPoint(geo),geo from devicelink WHERE "gid"=17178;

2)

SELECT ST_x(geo),ST_y(geo),geo FROM map.devices WHERE ip='192.168.1.1';

1)

POSTGIS="2.3.2" works correctly
