[postgis-devel] Spatial relationships not defined should return null

[Jose Carlos Martinez Llario]

Hi list,
According to the standards the spatial predicates which are not defined 
as st_touches (point , point) or st_overlaps (line, polygon) must return 
null.
PostGIS returns false in those cases (trunk and previous versions too), 
so it is against SQL/MM.

Should I open a ticket or this is the wanted behavior?

Regards,
Jose
