only be returning the part that intersects. You are missing a
WHERE clause unless you have just one raser tile, but still good
to have a WHERE anyway as a precaution. You'll know immediately
if you get no rows they don't even intersect.

You can speed up the intersect check by adding a functional
index geometry(geog) to your geography table
