I am sorry, I am out. Your code isn't much readable:
Minimally there isn't placeholder - some like $x
It is game for the most cryptografic code :).
You searching a functionality that isn't in pg now :(. Clause USING
doesn't work like macros or templates in C++
look on this page - maybe it could be useful for you
