the nadgrids-file, as used by proj4 to apply grid shifts to a
projection, should be installed for postgis? I produced one, put
it in the standard proj installation directory (/usr/share/proj),
and it works from the commandline with cs2cs. However, when I put
an entry in the postgis spatial_ref_sys table for a new projection
with this nadgrids file, the st_transform command says: "failed to
load datum shift file (-38). It also happens when I put in the
whole path. What should I do?<br>
