#3246: lwcollection_extract return object possibly referencing portions of
argument
---------------------+---------------------------
 Reporter:  strk     |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  medium   |  Milestone:  PostGIS 2.1.9
Component:  postgis  |    Version:  2.1.x
 Keywords:           |
---------------------+---------------------------
 Like with #3245, lwcollection_extract is another function that might
 return objects that depend on memory owned by its arguments. It uses
 lwgeom_clone over the input components, rather than lwgeom_clone_deep.

 Probably since 2.0.
