Well, then you really don't understand this at all then, so let's work on
that for a bit. http://www.postgresql.org/support/versioning is the
official statement, perhaps some examples will help clarify where and why
the line is where it is.
One of the first patches I ever submitted made a minor change to a contrib
utility used solely for benchmarking (pgbench) that added a useful
feature, only if you passed it the right parameter. That was considered
for a tiny bit before being rejected as a feature change too large to put
into a stable branch.
That was a small change in a utility that should never be run on a
production system. You're trying to get a change made to the code path
people rely on for their *backups*. Good luck with that.
The parable I enjoy pulling out in support of this policy is MySQL bug
where they added a seemingly minor optimization to something and
accidentally broke the ability to sort in some cases. There's always a
small risk that comes with any code change, and this is why you don't ever
touch working production code unless you're fixing a bug that's more
troublesome than that risk.
