The case "shut down master and standby, run pg_checksums on both, and
start them again" should be supported. That seems safe to do, and a
real-world use case.
Changing the system id to a random number would complicate this.
(Horrible idea: maybe just adding 1 (= checksum version) to the system
id would work?)
