I am using a PostGres/PostGIS 8.3 database with gt-epsg-postgresql
plugin. The EPSG Geodetic Parameter Dataset has been loaded into
postgres from EPSG version 7.6.
When I try to transform a geometry from EPSG:4326 (2D CRS) to EPSG:4979
(3D CRS) I get the following:
Caused by: org.opengis.referencing.operation.OperationNotFoundException:
No transformation available from system "EllipsoidalCS[Ellipsoidal 2D
CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree]"
to "EllipsoidalCS[Ellipsoidal 3D CS. Axes: latitude, longitude,
ellipsoidal height. Orientations: north, east, up. UoM: degree, degree,
metre.]".

It seems to me that 2D to 3D transform should be simple (just add a 0
value for Z axis). Is there a way to do this? If not, shall I file an
RFE? Thanks for your help.
