Comment(by pbalomiri):
Hi,
I got this bug too. I am working on os/x
The lib versions are:
{{{
template_postgis=# select * from postgis_version();
postgis_version
---------------------------------------
1.5 USE_GEOS=1 USE_PROJ=1 USE_STATS=1
template_postgis=# select * from postgis_proj_version();
postgis_proj_version
-------------------------------
Rel. 4.7.1, 23 September 2009
}}}
The Error consistently appears when using SRID 4326:
{{{
wien_python=# select st_transform(st_transform('srid=4326;POINT(1
1)'::geometry, 900913), 4326);
ERROR: transform: couldn't project point (111319 111325 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.
For SRID 4267, however it works
}}}
wien_python=# select ST_Transform('SRID=900913;POINT(653103 6.63036e+06
0)'::geometry, 4267);
st_transform
