ST_Transform failure

[georgevl]

Hi all,

Trying to execute the following:

SELECT ST_AsText(ST_Transform(ST_GeomFromText('POINT(2649262.94974021 4579345.79221865)', 3785), 4326))

I get:

NOTICE: 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.

ERROR: transform: couldn't project point (2.64926e+006 4.57935e+006 0): failed to load NAD27-83 correction file (-38)

Based on various comments I found floating around the web, I tried the environment vars plus copying the zip file etc etc.

The thing that strikes me as most important is that if I restart the PG Service and try the statement it works, but only once, all subsequent executions fail!

SELECT postgis_full_version();

Please update to PostGIS 2.0.0 final -- there have been some fixes to Proj4 error reporting.

Many thanks. Took me a while to figure out how but working now. Apologies.
