At the moment, EXECUTE just feeds the string it finds to spi_execute().
We could probably hack it to figure out how to modify FOUND, but I think
it would be ugly. One way to fix this would be to reimplement EXECUTE to
be essentially `eval': it would take an arbitrary string and execute it
as a PL/pgSQL statement. That would fix the FOUND problem, and also give
us EXECUTE INTO in one fell swoop. (Rather than reimplementing EXECUTE,
we might want to add this functionality as a new command -- "EVAL" might
be a good name for it.)

I think it's reasonable to assume that the application developer knows
this much.
