FWIW, As a user, I still would put my priorities more like Gavin did.
Replication/cluistering is top for me, followed by point-in-time
recovery. Row reuse would be good, although maybe I differ a little in
that I would like 'CREATE OR REPLACE' syntax a liitle more. ALTER TABLE
DROP COLUMN doen't do much for me - it's nice, but for the few case
where my DB design was not up to snuff, I just rename and carry the
column on until my next major upgrade.

Of course my say-so is moot. It's been my experience that people who
vote by suppying code tend to be weight somewhat more hevily in this
process. And I can't think of any way I'd rather have it.

Easy enough to do in middleware. Just in the fantasy world in which I
somehow spoke for developers' time, I still wouldn't mark this too high
on my priority list.

So there's a little user feedback for you. Hope it helps.
