[postgis-users] st_HausdorffDistance

[Bob Pawley]

Hi

I’m looking at st_HausdorffDistance.

When I run the example found at
 http://postgis.refractions.net/docs/ST_HausdorffDistance.html 

SELECT st_HausdorffDistance( 'LINESTRING (0 0, 2 0)'::geometry, 'MULTIPOINT (0 1, 1 0, 2 1)'::geometry);

I get the error  “No function matches the given name and argument types. You might need to add explicit type casts”.

Help will be appreciated.

Bob
