Hi Urs,
here is the download link for the new Loader version (will be part of 7.8.02.42):
In response to your questions:
1. Sequences should not be missing from the Export. Can you double check with the new Loader version?
2. Grants on functions are indeed missing - we will to bug fix this, but it might take some time...
3. And indeed the system table holding the execute rights on FUNCTIONPRIVILEGES is also missing - it seems this feature was not fully implemented - we will also address this problem and fix it.
Regards,
Thorsten
