I think most people (including those I had off-list discussions about
this with) were of the opinion that such an option should be there, so I
added an additional option NOVERIFY_CHECKSUMS to the BASE_BACKUP
replication command and also an option -k / --no-verify-checksums to
pg_basebackup to trigger this.

Updated patch attached.
