#1806 closed defect

Extremely slow and CPU-intensive ST_MakeValid case — at Initial Version

Reported by: strk Owned by: pramsey
Priority: high Milestone: PostGIS 2.0.1
Component: postgis Version: 2.0.x
Keywords: Cc:


The attached shapefile contains a single geometry. A multipolygon composed by a single polygon containing 4213 rings with a total of 82304 vertices.

The overall shape of the object resembles a line, with only 2 vertices. As shown in the picture (taken by qgis).

I'm not sure ST_MakeValid would _ever_ complete (didn't see it finish yet).
