#3777: POINT EMPTY, POINT 0 0 anomaly
----------------------+---------------------------
  Reporter:  robe     |      Owner:  pramsey
      Type:  defect   |     Status:  new
  Priority:  medium   |  Milestone:  PostGIS 2.3.3
 Component:  postgis  |    Version:  2.3.x
Resolution:           |   Keywords:
----------------------+---------------------------

Comment (by robe):

 strk yes, but that's not the point.  The bug is the empties are not
 collapsing into null and neither are the POINT(0 0) when you do a group
 by. Why is one POINT(0 0) not the same as the other POINT(0 0)?


 {{{
            txt            | count
 --------------------------+-------
  POINT(0 0)               |     2
  POINT EMPTY              |     1
  POINT(0 0)               |     1
  LINESTRING(0 0,0 1)      |     1
  GEOMETRYCOLLECTION EMPTY |     1
  POINT(0 1)               |     1
