IMHO use separate memory context will better and more fast way than 
freeObject(). I use this method in my suggested query cache and in the 
SPI (in SPI_freeplan()) and it is very good (without potential leaks).

All in backend/nodes are (IMHO) very dificult keep up and recursion is
and not gratis feature too. (Homework: write PG in Fortran :-)
