Yes. In the current code it is actually not possible for a single SQL
command issued by the client to give rise to more than one transaction.
(This might change if we invent some kind of stored-procedure engine, but
rules certainly can't do it.)

As Bruno pointed out, that really has nothing to do with how many
transactions are involved. The per-session state that currval uses will
sit quietly for as long as you need.
