For pg_checksums, probably some improvement patch will be submitted later, if someone feels like it.Let's see. I think that what we have now in v12 is good enough for checksum operations on an offline cluster. And my take is that we should focus more on online checksum verification for v13 and future versions.
I agree.For online, we should want throttling so that the check can have a reduced performance impact when scrubbing.
