The idea of backporting features scares me; I really doubt that you can
get enough beta-testing on a back branch to be confident that you
haven't broken anything with a feature addition.  In any case you'd be
quite limited in what you could do without forcing an initdb.

Another issue is that people expect dot-releases to be absolutely rock
solid.  If you start introducing new features then you considerably
increase the risk of introducing new bugs.  (I'm still embarrassed about
7.3.3's failure-to-start bug...)

Our past practice has been to back-port only bug fixes, and only
critical or low-risk ones at that.  I think this could be done in a more
thorough fashion, and it could be continued longer than we've done in
the past, but you shouldn't set the scope of the maintenance effort any
wider than that.
