The attached rebase with a PG_CONTROL_VERSION bump is what I have staged for
later tonight, submitting here to have the (hopefully) final patch archived as
well as another CFBot run.

Sorry for the late review. pg_enable/disable_data_checksums() aren't needed to be run 
on the standby. It appears the call would silently register a dynamic background worker that 
could never start , and could unexpectedly fire after promotion. 

Please find the attached patch to address this.

Thanks,
Satya
