[postgis-users] list of invalid geometries

[toni hernández]

Hello everyone,

I am writing an online postgis course and I would like a reference to 
all type of invalid geometries. Self-intersections, holes outside rings, etc
Does anyone know where I can find all possible invalid geometries?

Thanks in advance.
