Seems cool.  I am a bit worried about whether the transaction-block

to the FE/BE protocol to make this work correctly.

Agreed.  If I recall recent discussions correctly, the spec says that
certain SQL commands should open a transaction and others should not.
It's not reasonable to have that logic in psql rather than the backend.
