I've been notfied that GDAL-2.0 is not supported by PostGIS-2.0 so this is invalid.

I didn't know that. We should at very least amend the docs to note we don't support GDAL 2.0 in PostGIS 2.0.

I'm reopening this as a documentation bug.

Plan to put a note in docs and compatibility matrix — http://trac.osgeo.org/postgis/wiki/UsersWikiPostgreSQLPostGIS

​https://trac.osgeo.org/postgis/wiki/UsersWikiPostgreSQLPostGIS already says that.
