#2110 closed defect (fixed)

POINT(0 0) = POINT EMPTY != POINT(1 1)

Reported by: strk Owned by: strk

Description

This doesn't help analisys:

strk=# select 'POINT EMPTY'::geometry = 'POINT(1 1)'::geometry;
 ?column? 
----------
 f
(1 row)

strk=# select 'POINT EMPTY'::geometry = 'POINT(0 0)'::geometry;
 ?column? 
----------
 t
(1 row)

I suspect it has to do with bounding box of EMPTY being arbitrarily taken as 0,0,0,0

Let's not try to solve this in 2.0.2 unless you think it's a simple solution.

I'm not sure it's simple. It is the btree (bounding box based) comparison. I belive we did something low-level to fix the EMPTY=EMPTY case so maybe this one just isn't hitting the fixed path.
