Re: Press Release

Josh,

First of all, be aware that we have already collected half the translations
for the press kit. So at this point, we can only cut paragraphs and not
edit. These comments would have been more timely a month ago ....

How? Vacuuming does not require the database to be offline. Vacuum full
does, but that can be eliminated with proper tuning.

But reindex can now be eliminated if the FSM is tuned right.

And the whole point of the FSM feature is that most databases, with proper
tuning, should not require any maintainence which needs exclusive locking.

If anybody has evidence that the FSM index management doens't work, then we'll
cut the paragraph. However, I'm inclined to trust Tom & Co., and my only
simple tests seemed to uphold the Lazy-Vacuum-ability of indexes.
