Comment (by robe):

 This sounds an awful lot like this ticket #5984

 I recall whenever I saw the misbehavior - the SELECT
 _postgis_stats('nodes', 'geom','2') ; would spit out junk.

 I'm curious what yours shows @alexobs for your bad case.  I think we
 determined in that ticket too that 3.4 was good and 3.5 and above
 exhibited the bad behavior.
