Comment (by mcayland):

 Here is the output from another session:

 trunk=# SELECT
 ASTEXT(ST_Transform(ST_SetSRID(ST_Point(-633510.090428,7506727.67383),900913),4326));

 ERROR:  transform: couldn't project point (-305748 7.83449e+06 0): failed
 to load NAD27-83 correction file (-38)
 HINT:  PostGIS was unable to transform the point because either no grid
 shift files were found, or the point does not lie within the range for
 which the grid shift is defined. Refer to the ST_Transform() section of
 the PostGIS manual for details on how to configure PostGIS to alter this
 behaviour.


 So is the bug here that 4267 should work or perhaps the point is genuinely
 out of range?
