There's no plans for that, but if you provide a proper package, we can
include it.

We have plenty of non-core modules as packages.

That means that the packages on apt.postgresql.org should preferably
be in unstable as well, but that's not a hard requirement. You'll have
to argue with me if you don't want that, though ;)

Hmm that might be a bit of an issue - the source packages usually
support several PG versions in parallel, and then there's individual
binary packages built from that. But it's not like that's an
unsolvable problem.
