[postgis-users] st_clusterwithin fails

[Ronnie Lassche]

I’m trying to use the new st_clusterwithin function, but it keeps failing.



I’ve tried to cluster 20 points with the following query.



SELECT

                ST_ClusterWithin(geom, 50)

FROM winkels



Most of the times I get the message

“ERROR: Tolerance not defined

SQL state: XX000”

A few times it did work and gave me a result, but trying again will lead to
the same error.



I’m working with postgis 2.2.2dev (but also tried it with 2.2.0).



Anyone has a solution how to solve this?
