A replica should be able to pick up the intervening changes, assuming
you have enough speed and bandwidth to catch up.  No, you don't need
a complete re-sync or anything.  Just re-start the daemon that feeds
that replica.

There is not automatic switchover, BTW, so if you want to have one of
your replicas take over the read-write functions, you need to switch
over manually.
