[postgis-users] Operator does not exist: <<#>>

[Regina Obe]

I concur doesn’t seem to exist.  I’m trying to think how that would ever have been different from <#>.

 

I recall there was a time before we had true KNN for geometry that one was for bounding box distance and one was for the centroid bounding box distance.

 

Anyway I’ll remove from the docs.  Thanks for catching.

Hello everyone,

SELECT st_distance(geom, 'SRID=4326;POINT(1 2)'::geometry)
FROM ne_110m_admin_0_countries
ORDER BY (ST_GeomFromText('POINT(1 2)') <<#>> geom)
operator does not exist: geometry <<#>> geometry
Reference https://postgis.net/docs/manual-dev/en/geometry_distance_box_nd.html


Checked the postgis.sql.in <http://postgis.sql.in>  source code definition and did not find this operator. Has it been abandoned?

Thanks,
Dapeng
