It's possible you could use the "transition table" (aka
EphemeralNamedRelation) infrastructure for this, though I'm not sure
if it's really a close fit, or whether it's been built out enough to
support this usage. From memory, it wants to work with tuplestores,
which are a bit heavier-weight than SPITupleTables.
