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 by the 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,
