Here is a documentation patch I have applied to clarify that --analyze
does analyze during vacuum, not instead of vacuum.

I don't see this committed, but I would vote against it, because the
wording makes it sound like the statistics are for use by the optimizer
during vacuum.

I agree with your analysis. I have applied a simpler wording
improvement that just adds the word "Also".
