Ok, the documentation make sense now. I wonder what the performance
impact is. Probably, nobody cares about microoptimizing CREATE TABLE
statements. But BEGIN/COMMIT could matter. However, whatever you do in
between the BEGIN and COMMIT will already be jumbled, so you're already
paying the overhead. Hopefully, jumbling such simple commands will have
no noticeable overhead.

In other words, we should test this and hopefully get rid of the
'string' method.
