[postgis-users] missing SRID and distance in meters

[Paul Ramsey]

102003 is not an EPSG number, and we only included EPSG projection  
definitions in the shipping spatial_ref_sys.sql file.  102003 is a  
number ESRI assigned to that projection.  I suppose we could include  
the ESRI numbers in an upcoming release (hard call, but they did  
avoid conflicting with the EPSG numebrs).  In the meantime, just  
insert an appropriate record into spatial_ref_sys.
