Imho you should take a close look at StartUpId, I think it is exactly this
"large number". Maybe you can add +2 to intentionally leave a hole.

Once you increment, I think it is very essential to checkpoint and double
check pg_control, cause otherwise a crashrecovery would read the wrong xlogs.

Yes :-)
