While these are all comforting points, I *know* about analyze and I
occasionally forget. It just seems like a nessisary step after restoring
a backup. Conceptually, one could consider it just as important as an
index, i.e. the system will perform poorly without it.
From an "ease of use" perspective, it would be one less step.
