Re: CREATE TABLE LIKE INCLUDING PRIVILEGES

My interpretation of that message was not to go in this direction:

And I do see some issues in that regard with this patch:

With these changes, `INCLUDING ALL` requires ownership. I don't think
that's an acceptable breaking change? I also don't see a good way to
deal with that:

* either INCLUDING ALL doesn't include this - which would be confusing
* or it doesn't include this for non owned tables - even more confusing
* or it ignores ownership, which would be insecure

do you have a better suggestion?

There's also a privilege escalation issue in the current patch: if any
of the privileges have GRANT option, all of them will have in the new
table.
