Hello,
I had the same problem descriped in Issue 249. So I created a patch
that is working for me. It's not realy pretty but it's working. Maybe
someone has a better Idea how to fix this or can integrate this in the
production code. I also removed the schema name from the table name. A
thing I always had to do manualy.
