There are two relevant indexes in that table: one on (repo, time) (repo = user's DID), and one on just (time). Roughly speaking, for those users who follow e.g. 80 or 200 people, it makes more sense to scan the (repo, time) index those 80-200 times and collect the 100 most recent posts from all of those found, and for those who follow e.g. 9000 (yes, that happens 😛), it's faster to scan the single (time) index until you find 100 relevant posts. But I've been struggling to make Postgres always use the right index.
