Hi,
I have an unexpected 5 mins window to do a first reading of the patch,
so here goes the quick doc and comments proof reading of it. :)

Great! We have pg_ctl init[db], I think we want pg_ctl clone or some
other command here to call the binary for us. What do you think?

Consistency is good.
Now, basic first patch reading level review:
I think doc/src/sgml/backup.sgml should include some notes about how
libpq base backup streaming compares to rsync and the like in term of
efficiency or typical performances, when to prefer which, etc. I'll see
about doing some tests next week.
+ <term><option>--basedir=<replaceable class="parameter">directory</replaceable></option></term>
That should be -D --pgdata, for consistency with pg_dump.
On a quick reading it's unclear from the docs alone how -d and -t leave
together. It seems like the options are exclusive but I'd have to ask…
+ * The file will be named base.tar[.gz] if it's for the main data directory
+ * or <tablespaceoid>.tar[.gz] if it's for another tablespace.
Well we have UNIQUE, btree (spcname), so maybe we can use that here?
