Running --analyze-in-stages on a database with statistics causes the statistics to become significantly worse before they are improved. This could be made clearer in the documentation.
I think the paragraph you modified *already* stated that usefulness of
--analyze-in-stages (newly populated from a restored dump or by pg_upgrade). I
don't think your change is an improvement for --analyze-in-stages description.
If you read the previous paragraph, it explains _how_ (3 stages of ANALYZE with
different settings) and _why_ (produce usable statistics faster).
