#3253: ST_3DMaxDistance curved geometries mixed dimension yields DIST_MAX mode not
supported
---------------------+---------------------------
 Reporter:  robe     |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  low      |  Milestone:  PostGIS 2.2.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 Running thru garden tests, and just noticed this. I'm not sure if this is
 bug or not, but message is very confusing.

 }}}


 returns error:


 {{{
 NOTICE:  One or both of the geometries is missing z-value. The unknown
 z-value will be regarded as "any value"


 ERROR:  lw_dist2d_ptarray_ptarrayarc does not currently support DIST_MAX
 mode
 ********** Error **********

 ERROR: lw_dist2d_ptarray_ptarrayarc does not currently support DIST_MAX

 }}}

 In PostGIS 2.1.8 it returns:

 {{{
 ERROR:  Unsupported geometry type: CircularString
 ********** Error **********

 ERROR: Unsupported geometry type: CircularString
 SQL state: XX000


 }}}

 Now I'm unclear do we support curves in 3D now with the 3D functions?

 PostGIS 2.2 returns 0.


 In PostGIS 2.1.8, I get

 {{{
