  Component:  PostgreSQL Provider  |     Version:  3.5.0                                              
   Severity:  2                    |    Keywords:  PostGIS PostgreSQL axis direction coordinate system
External_id:                       |  
-----------------------------------+----------------------------------------
 The PostgreSQL provider's FdoISpatialContextReader implementation
 retrieves the Coordinate System WKT from the PostGIS catalog column
 spatial_ref_sys.srtext. These WKT's can contain clauses to change the
 direction of the X and Y axes from X-East, Y-North. For example EPSG:31254
 sets X to North and Y to East.

 However, PostGIS uses the proj4 library for coordinate system handling.
 proj4 does not reassign the axes so PostGIS handles geometries for all
 coordinate systems as X-East, Y-North.

 Given the above, the PostgreSQL provider should remove the axis
 assignments for the WKT's that it exposes to be consistent with the actual
 geometry values.
