Hi everyone

Can someone please tell me why transforming a point from ED50 to WGS84 seems
to give the exact same result as the input data ?

SELECT ST_AsText (ST_Transform (ST_GeomFromText('POINT(-72.0 42.0)',4230),
4326))

This gives

POINT (-72 42)

I'm using Postgresql 9.0 :

"POSTGIS="1.5.1" GEOS="3.2.2-CAPI-1.6.2" PROJ="Rel. 4.7.1, 23 September
2009" LIBXML="2.6.32" USE_STATS"

Thanks,
Anders
