You need to store the collation version(s) for each index. This thread deals with the problem: https://commitfest.postgresql.org/29/2367/ https://www.postgresql.org/message-id/CAEepm%3D0uEQCpfq_%2BLYFBdArCe4Ot98t1aR4eYiYTe%3DyavQygiQ%40mail.gmail.com That's not all of it as you would still need some filtering capabilities in the backend to reindex only the collation-sensitive indexes with a reindex, but that's one step forward into being able to do that. -- Michael
