[postgis-users] Equality operator for type box2d

[Nick Ves]

I was playing with the ST_Extent today and I wanted to try a query like this:

select distinct ST_Extent(geom)  over () box from parcels_test

where the geom is Type ST_Polygon but I got this error instead:

  ERROR:  could not identify an equality operator for type box2d

The aim was to get the BBox from a set of polygons that might or might
not be adjutant. Ofc you can get the same results by limit the result
to 1 but, it hitted me strange box2d type not having an equal operator
