That seems rather cumbersome. pg_basebackup is a run once, and then it
dies. The slot would have to be created before running pg_basebackup,
and destroyed manually.
It would make sense to provide a new option that would tell the server
to recycle segments until they've been sent to this client, or until the
client disconnects. But that would look quite different from
pg_receivexlog's --slot option.
