Description

The transformation parameters between S42 and WGS84 datums wihch are listed inside the EPSG:3844 definition (TOWGS84[33.4,-146.6,-76.3,-0.359,-0.053,0.844,-0.84]) are valid for Poland, not for Romania. You can see this in the EPSG database: Coordinate Transformation with code 1645: Area of use = Poland - onshore.

The correct parameters for datum transformation in the case of EPSG:3844 are listed in the EPSG database with coordinate transformation code = 15995. These are: 2.329,-147.042,-92.08,0.309,-0.325,-0.497,5.69

I've created  http://trac.osgeo.org/geotiff/ticket/52 , since those kind of issues originate from libgeotiff, and then cascade to GDAL and PostGIS. At the next EPSG refresh, there's a risk of that change to be lost if not fixed in libgeotiff.
