#6026: Distance operator <-> returns "tuple order" error
----------------------+----------------------------------------------
Reporter: dirc | Owner: pramsey
Type: defect | Status: new
Priority: medium | Milestone:
Component: postgis | Version: 3.5.x
Resolution: | Keywords: distance, operator, tuple, order
----------------------+----------------------------------------------
Comment (by pramsey):
So, doing a little digging into the debugger, I find that:
* The index distance between the bounds of the polygon and the point is
exactly 778.
* Meanwhile, the "exact" distance between the polygon and the point is...
less.
{{{
SELECT ST_Distance(
'LINESTRING(132700 490000, 133894.531 490000)',
'POINT(133718 489222)'
);
st_distance
-------------------
777.9999999999999
}}}
