They're written in C. You can't simply "CREATE FUNCTION ..." them in an
older version of Pg.
You could possibly port them to an older version as an add-in module
(using pgxs to build it), then load them as C functions. I would be
reluctant to try that myself, though, since you'd just be throwing the
work away when you upgrade.
