Re: Best "how to index" docs/books

Hello Kyle,
not really a book but Lothar Flatz did such a project in the past and has written an article about it in DOAG/RedStack magazine ( https://www.doag.org/formes/pubfiles/6663723/2015-01-News-Lothar-Flatz-Faktenbasierte-Indexierung-ein-Erfahrungsbericht.pdf ).

Not quite sure how good your German skills are for reading this article but you may also can get in touch with him directly ( https://twitter.com/LotharFlatz ) :-)

> The first past approach is just to look at execution plan, see where there are full tablescans scanning significant # of rows or blocks with predicate or join filters that filters out most of the rows. Then extending that index opportunity to other SQL and seeing which columns might be included in the index and what order. I like this description from a PostgreSQL extension  https://rjuju.github.io/postgresql/2020/01/06/pg_qualstats-2-global-index-advisor.html.
