Sounds like we have to refactor that code a bit.  Or maybe it should
just be a separate code path.  The current plpgsql compiler is also
pretty intertwined with stuffing all the information about the function
into a persistent memory context, which is something we most definitely
*don't* want for an anonymous code block.  So it's going to take a bit
of work there.  I think pulling the heap tuple apart might be the least
of your worries.
