The problem, I think (and please note that I'm not against it, just
playing major devil's advocate here) is that there have always been some
major fundamental coding changes between releases that there are very few
patches that are "back-patchable" without having to do some heavy
re-writes ...

Using Linux/FreeBS/Insert OS Here as an example is like comparing apples
to oranges ... take FreeBSD as an example, since I know it ... 5.x has had
some *major* re-writes to the kernel done to it, getting rid of 'the Giant
Lock' that SMP in 4.x uses ... those changes are not back-patchable, since
then you'd have 5.x ... there are alot of changes to the 5.x kernel that
rely on those changes, and are therefore not *easily* back-patchable ...

Now, userland software is a totally different case, since they are rarely
"tied" to the kernel itself ...

Think of PostgreSQL as the kernel, not as the distro ... how many changes
from one kernel release ae easily patched into an older one, without
having to take alot of other baggage back with it ... ?

I don't believe anyone would work against this, nor could I imagine that
anyone would think it was "a bad idea", I'm just curious as to how
possible it is to do ...
