Hmm ... the planner does have the ability to do that sort of thing (we
use it for cursors).  SPI_prepare doesn't expose the capability.
Perhaps adding a SPI_prepare variant that does expose it would be the
quickest route to a solution.

I get a headache every time I look at the RI triggers ;-).  Do they
always know at the time of preparing a plan which way it will be used?
