I believe it can be done technically, though basically the function will
need to be re-written for the purpose. It isn't as simple as adding an
explain somewhere since the output of explain is a result set. But as you
are already using pl/pgsql then your parameters can just be done up as
variables instead and that query should be able to be explained.
