Description

Should EMPTY be within Infinite distance from EMPTY ? Phylosophically, maybe, but … for any practical reason, does it make sense to return true on that case ?

Replying to strk:

Seems too nit-picky to me. I think ST_DWithin(geomA, geomB, *) should always be FALSE if either argument is EMPTY.

In 0394036c/git:

Have ST_DWithin with EMPTY operand always return false

Ok, fixed in master branch. I guess we could want to backport this

Not backporting, so this is closed in 3.2.0
