Segfault in prefetch worker when replicating an insert that creates a database implicitly

      I attached the diff on my branch. Just added a test and changed one other file which allows the upgrade to actually upgrade (otherwise it restarts with 2.6 again). Add the one change and the test, and run the test.

      I attached the diff on my branch. Just added a test and changed one other file which allows the upgrade to actually upgrade (otherwise it restarts with 2.6 again). Add the one change and the test, and run the test.

      When I run the attached test, the attached log results. In there is a seg fault after restarting a 2.6 node as a 2.8 node.

      segfault:
