The replicas will need to be rebuilt after the restore of the primary.
There's a few different ways to do that, but the fastest that I'm aware
of would be a pgbackrest delta restore of all the systems using an
appropriate backup set (which pgbackrest will figure out for you when
you tell it the time you want to restore to).
