Its a giant bummer that there's no way to upgrade a postgres cluster to support WAL checksums. You have to enable them at init and then dump/restore. There's a huge speed difference between dump/restore and pg_upgrade with hard links. I bet the adoption rate of checksums stays really low because of this.

@foozmeat honestly it should just be on by default, it's like a 1-2% performance impact. That's basically nothing once you factor in the typical performance improvements you get with new releases
