Comment(by strk):
Maybe for long edges it might be faster, but you have to take into account
the conversion to geos too (in the ST_Intersects case) and the
ST_Intersects computes full intersection matrix too, which means no early
exit ever happens.
Would be interesting to hear Nicklas opinion (but even better: profile
data) on the matter
