I do not like the idea of breaking existing upgrade scripts,
especially not by requiring them to use a parameter that older
vacuumdb versions will reject. That makes it impossible to have a
script that is version independent. I really doubt that there is any
usability improvement to be had here that's worth that.
How about causing "--analyze-in-stages" (as currently spelled) to
be a no-op? We could keep the behavior available under some other
name.
