Yes, sorry, I had a moment of brain fade yesterday. However, I think
we're a bit under-documented on the pg_basebackup page, regarding both
tar mode and tablespace_map (which isn't even mentioned).
And there is this which I noticed this morning: the
--tablespace-mapping feature of pg_basebackup seems to be quite broken
in --format=tar mode - it simply has no effect AFAICT. I assume it was
broken before, but we should either fix it (possibly hard) or disallow
the combination (which would be a pity).
I'm going to go ahead and commit this in the state I have it now,
because for the most part these are preexisting deficiencies.
One more thing: I think pg_basebackup will now not work in tar mode with
pre-9.5 servers, since it will be using an unrecognized option of the
BASE_BACKUP protocol command. If so that certainly needs to be
documented and release noted.
cheers
