Hi José,

ogr2org can import excel files for you.  http://www.gdal.org/ogr/drv_xls.html  
Or you compile gdal/ogr from svn then you can also import xlsx files. http://www.gdal.org/ogr/drv_xlsx.html

Hi Richard,

a transformated height are no "artifact". You can only get one by using 7
parameter transformation. Using the 3 parameter transformation (cartesian
coordinate system) or nadgrid can not change the z value.

I think the better way is having a function ST_Transform2D() and the normal
ST_Transform(). A function named ST_Transform3D can't be satisfied if the
proj4text having nadgrid or only 3 parameter defined.

Hi Steve,

you only need to enable postgis for public schema. In every other schema the
geography typ will be used as public.geography.
