Yeah, I know, I had been thinking it might be nice to not do that at
some point in the future, but thinking on it further, we've already got
a "pick up where you left off" capability with pgbackrest, so it's
really not a huge deal if the backup fails and has to be restarted, and
this does remove the need (or at least deprecate) to use the "stop an
already-running backup if you find one" option that pgbackrest has.

Thanks!
