Hi,
Does anyone have a clue why this fails:
select contains(geomfromtext('POLYGON((0 0,0 8,8 8,8 0,0 0),(3 3,5 3,5
5,3 5,3 3))'), geomfromtext('POLYGON((0 0,5 0,5 1,0 1,0 0))'))
;
contains
----------
f
(1 row)
Without the Hole in the polygon
select contains(geomfromtext('POLYGON((0 0,0 8,8 8,8 0,0 0))'),
geomfromtext('POLYGON((0 0,5 0,5 1,0 1,0 0))'))
;
contains
----------
t
(1 row)
And the Hole does not intersects the other polygon
select intersects(geomfromtext('POLYGON((3 3,5 3,5 5,3 5,3 3))'),
geomfromtext('POLYGON((0 0,5 0,5 1,0 1,0 0))'))
;
intersects
------------
f
