#5401: ST_Differnce silently giving us wrong results
----------------------+---------------------------
 Reporter:  laopsahl  |      Owner:  pramsey
     Type:  defect    |     Status:  new
 Priority:  medium    |  Milestone:  PostGIS 3.3.4
Component:  postgis   |    Version:  3.3.x
 Keywords:            |
----------------------+---------------------------
 In this case, we have a fixed restricted area (blue),  where users can
 select an area to use that are not already used by another user (red
 area), so we need to remove the area taken. The result the user saw is
 here https://gitlab.com/nibioopensource/resolve-overlap-and-
 gap/-/blob/develop/src/test/pictures/difference_test_01_POSTGIS_3_3_3.png
 (output from ST_Difference, the green rectangles).

 The ST_Difference test and data used can be found here
 https://gitlab.com/nibioopensource/resolve-overlap-and-
 gap/-/blob/develop/src/test/sql/regress/rog_sf_difference.sql .

 If a I use latest source compiled by Sandro a couple weeks ago on a server
 locally, this test case works, but then another test case fails longer
 down in the script.
