That is a good point; I think there is a spatial check for equality used
for "the_geom". For information on the difference between equals and
equals see this page:
- http://docs.codehaus.org/display/GEOTDOC/02+Geometry+Relationships
I am more concerned with the interger case; can you give some specific
examples? The "converter" stuff
used to prep the data for the equality check tries to adapt the data to
the same type before checking. So 1 = "1" should
work out as true.
