I'm fairly confident that I overlooked single row mode entirely in the
original patch, though it's long enough ago that it's hard for me to
remember exactly.

I don't really have much of an opinion on the best handling of it.

I would expect to be setting single-row mode just before I requested
the *result* from the next pending query, since it relates to result
processing rather than query dispatch. But that's about all the
opinion I have here.
