Agreed, nice simple and uncontentious patch.

All good apart from two minor things:

* doc page needs to explain what IF EXISTS does, like DROP TABLE, e.g.

IF EXISTS   Do not throw an error if the table does not exist. A notice is
issued in this case.

* the error message is "does not exist" rather than "does not exists",
which means the code, a comment and a test need changing

Other than that, happy to apply as soon as you make those changes.
