Curtis Barrett (curtis(at)northwestern(dot)edu) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
path ?# path

Long Description
nothing major. the ?# (geometric intersection) operator for paths iterates over point pairs in each path testing for intersection. however, it ignores the last->first point pair for closed paths. a quick workaround is to tack the first point on the end of a closed path.

Sample Code
# select '((1,1),(2,0))'::path ?# '((0,0),(0,2),(2,2))'::path;
(1 row)

# select '((1,1),(2,0))'::path ?# '((0,0),(0,2),(2,2),(0,0))'::path;
(1 row)
