#4363: Create ST_3dIsValid function
---------------------------------+---------------------------
 Reporter:  johnpowell           |      Owner:  pramsey
     Type:  enhancement          |     Status:  new
 Priority:  medium               |  Milestone:  PostGIS 2.5.3
Component:  postgis              |    Version:  trunk
 Keywords:  isvalid, 3d, sfcgal  |
---------------------------------+---------------------------
 The existing Postgis ST_IsValid function only works in 2D, as can be seen
 from:

 SELECT ST_IsValid('LINESTRING Z (0 0 0,0 0 10)');
 NOTICE:  Too few points in geometry component at or near point 0 0 0


 sfcgal contains a 3D IsValid function, which could be used for this
 purpose, see,
