Yes.  There are some poorly-worded places in the docs that make it sound
like they might be completely separate operations, but they're not.

I would like to split out ANALYZE as a separately-callable command at
some point, but we'll no doubt continue to offer the combined "vacuum
analyze" command, if only for backward-compatibility reasons...
