Thanks for the info @RGJ!

The PR for removing the NULLS NOT DISTINCT OPTION is up:

### What is this change? We added `NULLS NOT DISTINCT` to a unique index on `…problem_check_trackers`. This option is only available in PG15+. It does not in itself break PG13, but restoring a PG15+ backup to PG13 currently errors out. It seems this is an operation that's more common than we first thought. This commit fixes that by removing the `NULLS NOT DISTINCT`. ### Don't we need it, since we added it? We already have another, backwards-compatible approach to do the same thing in place, so this shouldn't change existing behaviour.
