I have sets of points (up to 250,000 in a set) and I want to get the
furthest distance between any of them.
In theory the simplest way is to use
ST_MinimumBoundingCircle(ST_Collect(geography) and then get the diameter
of that.
Hi Rémi,
have you taken a look at ST_GeoHash ?
It might be a good candidate for your constraint exclusion check.
There are restrictions though. Coordinates must be in lat/lon for instance.
