I've gotten to the point of (relatively) high-cost coding/testing.  The
removal of checkpoint_segments and pause_on_recovery are leading to
refactoring of not only the regressions tests but the actual backup
code.  9.5 and 8.3 are the only versions that require exceptions in the
code base.

I've already done basic testing against 9.5 by disabling certain tests.
 Now I'm at the point where I need to start modifying code to take new
9.5 features/changes into account and make sure the regression tests
work for 8.3-9.5 with the fewest number of exceptions possible.

=46rom the perspective of backup/restore testing, 9.5 has the most change=
s
since 9.0.  I'd like to know that the API at least is stable before
investing the time in new development.

Perhaps I'm just misunderstanding the nature of the discussion.
