Funny this does work when I include st_box2d as in -
st_within( graphics.point_grid.the_geom,
st_box2d(library.dgm_process.the_geom))
However, this will include points within the box yet outside of the actual
geometry.

I have tried it with the point and geometry reversed with the same

Perhaps, I am not looking at this the right way.
According to the manual
st_within Returns TRUE if geometry A (points) is completely inside
geometry B ( geometry).
If it scans the list of 858 points some of those points are within the
geometry - unless Postgis is looking at the 858 points as one entity.
Ooops, sorry, indeed you were right and used the function the right way.
:)
Could you provide an example of a geometry & some points you're using ?
You might also try ST_Intersects or ST_Covers.
