It'd probably have to be done at CREATE DATABASE time, like the setup of
the database encoding is.
Personally I can't say I really see the point. I suspect database
designs that rely on the sort order of NULL anyway - they usually seem
to be trying to use null as a concrete value rather than an "unset/unknown".
Even if that's not the case here, I suspect (OP) that you'd have to
produce a viable patch for this feature if you want it supported, as I
doubt there'll be enough interest for anyone else to want to implement it.
