You're putting an awful lot of weight on an unsupported assertion about
latency. If a user cares about that, why would she not simply merge the
commands into "SELECT 1, 2, 3 \into one two three" ?
And I still say that what you're proposing might be easy right now, but
it might also be next door to impossible in a refactored implementation.
I don't think we should go there on the basis of a weak argument about
latency. \into should retrieve data only from the last PGresult.
