You need to store the collation version(s) for each index. This
thread deals with the problem:
https://commitfest.postgresql.org/29/2367/

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.
