*Two new functions are added, pg_enable_data_checksums() and

in turn will start one sub-worker (“checksumhelper worker”) in each
database (currently all done sequentially).*

This is at least the fourth version of the pattern launcher plus worker
background workers.  I wonder whether we can do something to make this
easier and less repetitive.  Not in this patch, of course.
