Hmm, I thought we explained that in the manual, but I can't see it. I
think we should add a note to the ref page of PREPARE TRANSACTION,
something like:

"PREPARE TRANSACTION is not intended for use in applications or in
interactive sessions. It's purpose is to allow an external transaction
manager to perform atomic global transactions across multiple databases
or other transactional resources. Unless you're writing a transaction
manager, you probably shouldn't be using PREPARE TRANSACTION"
