#4131 closed defect (fixed)

ConcaveHull sfcgal test lost

Reported by: komzpa Owned by: robe
Priority: medium Milestone: PostGIS 2.5.0
Component: postgis Version: master
Keywords: Cc:


In a switch to sfcgal backend got lost.

Switch should be returned into its place, and probably \i concave_hull.sql.

After that probably will show up once again.

Just a note on my local after turning on sfcgal, still waiting for concave hull test to finish.

Almost tempted to turn off sfcgal inside the function :)

Resolution: fixed
Status: newclosed

In 16659:

put back old sfcgal test (except use \i, and have the query be what was in sfcgal one), the sfcgal one was different
Closes #4131
Revise ST_ConcaveHull to use ST_UnaryUnion(ST_Collect..) (cause I know sfcgal doesn't replace with it's own implementation / a bit of a cheat)
Take out some ST_Union calls I think are over compensating.
References #3638

Forgot to mention I left in Komzpa's new crueler (realer) test for ST_ConcaveHull, but not bothering to have it run in SFCGAL (it might run reasonably now), but I called it
