How do I cut a single line with polygons (in several segments) so that each cut line take data from the polygons? Something like a centroid takes.

ST_Polygonize will do the job:
CREATE VIEW boundarypolygons AS
SELECT
g.path[1] as gid,
g.geom::geometry(polygon, 31492) as geom
FROM
(SELECT
(ST_Dump(ST_Polygonize(geom))).*
FROM boundary
) as g;
Feature To Polygon will slice polygons by line feature classes when you use the two feature classes as its input.
Inputs:
Results:
Depending on line geometry this method can create excess polygons. If so, clip your output feature class by your original input polygon feature class to eliminate the new polygons.
If you only want certain polygons sliced by certain lines, use an SQL expression and feature layers to limit your inputs.

Since this appears to solve the users problem Ill add it here.
In ArcGIS and QGIS The intersect tool splits the lines at the polygon boundaries and does keep the attributes of each line feature as well as adds in the attributes of the polygon feature that it lies in if the Join Attributes selection is set to ALL.
