I think we can get started with the initdb --no-data-checksums option.
The 0001 patch is missing documentation and --help output for this
option. Also, some of the tests for the option that are in patch 0003
might be better in patch 0001.
Separately, this
- may incur a noticeable performance penalty. If set, checksums
+ may incur a small performance penalty. If set, checksums
should perhaps be committed separately. I don't think the patch 0003
really changes the performance penalty. ;-)
