I've looked this version.
The only reservation I have is that when changing the owner of a schema,
the new owner is not always checked. I would suggest to query the new
owner to check that it matches (5, 11, 12), just as you do in 3.
Also, reowning is tested several times (5, 11, 12). I would suggest to
remove 12 which does not bring much new things after both 5 and 11 get
passed ?
Otherwise the patch applies (with a minor warning about spaces on line 33)
passes for me, and brings valuable new test coverage.
