our insertion order is of course != index order otherwise the question would have been trivial.

Hello,We have large tables with billions of rows in them and want to take advantage of the BRIN index on them.Issues we are facing:
- as I understand, BRIN index is useful only if the data is stored in index order. As an example we want to create a composite BRIN index on 3 columns - integers and strings (varchar). How can we tell Postgres to store data in index order as new records are inserted into the database?
- i understand that turning on autosummarize will keep the index fresh and up-to-date as new records are inserted. is this correct?
Thanks for your help.S.
