Actually, just to correct this list:
* there are no tools from Sun
* pgPool2 does not deal with recovery.conf
* there are additional ones: WAL-E, etc., which may or may not need to
be edited.

FWIW, I've already found that I have to modify all my backup scripts for
9.0 from 8.4, and again for 9.1 from 9.0. So we do break backwards
compatibility, frequently.

I'm happy to make upgrades easier, but I want a path which eventually
ends in recovery.conf going away. It's a bad API, confuses our users,
and is difficult to support and maintain. If you think it's easier on
our users to do that in stages over several versions rather than in one
fell swoop, then let's plan it that way.
