When the set-returning-function feature was written originally, years
ago, the tuple at a time mode did really work tuple at a time. But it
had issues and was axed out of the patch before it was committed, to
keep it simple. The idea was to revisit it at some point, but it hasn't
bothered anyone enough to fix it. It's basically "not implemented yet".
