You mean like this?
SELECT ST_Intersection(

ST_Expand(pt.geom, 2))
FROM mypolygontable poly, mypointtable pt
WHERE poly.geom && ST_Expand(pt.geom, 2);
Yes, you can expand the bounding boxes on fly and use it to intersect
another geometry.

Your request nr.2 is perfect, thank you.
But can use this created polygon to selcet a part of another polygon,
in my case public.wald_by.the_geom.
Or do I have to save the selcted information in a table and use this
for the new request???
Because I need to selcet the other polygon to calculate the area of
the selected part, of public.wald_by.the_geom !

It works, thx
