 r9647 takes care of the segfault.  There is still the matter of handling
 the query into spatial_ref_sys.  If auth_name isn't 'EPSG', the logic
 still returns an error without trying proj4text or srid.

 At the moment, with the default contents of spatial_ref_sys, that's only a
 problem for srid=900913, auth_name="spatialreferencing.org".  I suppose
 those people can use srid=3857 instead.  In my case, for a custom srs with
 no auth_name, I will still get the error.  rtpg_getSR will never try my
 proj4text or srtext strings in GDAL.

 It looks like GDAL's SetFromUserInput() will take EPSG: as well as EPSGA:
 and ESRI: and several other versions of shorthand.  I'm not sure how many
 other people add their own entries into spatial_ref_sys.  If they do, and
 if the auth_name is ESRI, or EPSGA, or null, they'll run into this.
