There's a osr.GetCRSInfoListFromDatabase() method in the SWIG bindings (binding of OSRGetCRSInfoListFromDatabase()), but it is only exposed for the Python bindings currently. A new SWIG typemap should be written for the other binding languages, so that osr.GetCRSInfoListFromDatabase() can be used with them.
