#1806: Extremely slow and CPU-intensive ST_MakeValid case
---------------------+------------------------------------------------------
Reporter: strk | Owner: pramsey
Type: defect | Status: new
Priority: high | Milestone: PostGIS 2.0.1
Component: postgis | Version: 2.0.x
Keywords: |
---------------------+------------------------------------------------------
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).
