Here are some comments on docs.

- There's no docs for pg_mv_statistic (should be added to "49. System Catalogs")

- The word "multivariate statistics" or something like that should appear in the index.

- There are some explanation how to deal with multivariate statistics in "14.1 Using Explain" and "14.2 Statistics used
bythe Planner" section.
 

I am now looking into the create statistics doc to see if the example
appearing in it is working. I will get back if I find any.

Best regards,
