Case in point: even though the Debian upgrade scripts have occasionally
given me a near-heart attack by claiming that they didn't succcessfully
upgrade when they did, I've never had this problem. Is this because
Oliver is smarter than you? Or Debian is 'superior'? No, it's because
_incremental upgradability_ is _the_ design goal for the Debian
distribution. Lots of other stuff may work better on RedHat (auto
hardware detection, etc.) but this is the design case for Debian, so
the facilities are mostly there for Oliver to use to do incremental,
rollbackable, upgrades.

What does that mean for PostgreSQL? Perhaps Tom's right: you can't fix
it in the program if the underlying system doesn't support it.
