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?
