Yeah this is my basic confusion. But wouldn't the arguments be
evaluated afresh on the subsequent call for this SRF? In that case
freeing up the context of the *last* call should not be an issue I
would think.
And if this is indeed the case we should be using a different longer
lived context and not the ecxt_per_tuple_memory context..
