> If the values are perfectly clustered, the index is optimal because you scan the minimal set of pages. That's the bit I'm particularly interested in, as my plan would be to keep the pages well clustered: http://dba.stackexchange.com/a/66293/1396 Do you see any blocker preventing BRIN being used for a continuous background re-clustering job (in parallel with or as part of vacuum), similar to the mechanism I experimented with before? If not is this something there might be support for adding to the TODO list?
