#1230: _ST_BestSRID should not return negative SRID values
 Reporter:  strk     |       Owner:  pramsey      
     Type:  defect   |      Status:  new          
 Priority:  high     |   Milestone:  PostGIS 2.0.0
Component:  postgis  |     Version:  trunk        
 Keywords:           |  

Comment(by strk):

 I've a patch ready to commit. The patch:

  1. Writes a set of defines in libpgcommon/lwgeom_transform.h for the
 reserved SRID values
  1. Uses the macros from _BestSRID
  1. Uses the macros from ST_Transform

 There were tests in tickets.sql for the correct functioning of UTM zones
 (thanks robe) so that part is tested. I noticed _BestSRID _never_ returns
 the Polar Stereographic projections.

 The patch is attached here, if you want to review.
