What do you think of the attached wording?

I don't think the pipeline angle is of concern to anyone who might be
reading these comments with the aim of understanding what guarantees
they have.  Perhaps there should be more about that in the user-facing
docs, though.

Commits

  1. Rethink handling of [Prevent|Is]InTransactionBlock in pipeline mode.

  2. Doc: add comments about PreventInTransactionBlock/IsInTransactionBlock.

  3. Force immediate commit after CREATE DATABASE etc in extended protocol.
