Mitchell,
If you look in the documentation, you'll see that the streaming mode
requires a second replication connection. So, how would you
integrate two separate channels into one tar input? Also, as the
stream and backup aren't synchronized, there wouldn't be any way to
isolate those in a tarball. True, they don't explicitly call this
out, but if you think about it only the -X f mode (fetch) makes any
sense. This is why I always use the fetch mode when writing to tar.
FWIW,
Jay

Hi,
In regards to pg_basebackup, I want to use "--format=tar"
(for the purpose of sending the backup to stdout) but when I
also try to use "--xlog-method=stream" to include some WAL
files (without worrying about the wal_keep_segment parameter
on the server) it tells me "wal streaming can only be used in
plain mode".
I can't find any documentation regarding this conflict
between "--format=tar" and "--xlog-method=stream". Can anyone
provide any insight into why this combination is forbidden, or
where it might be documented? Are there plans to support this
combination in the future?
Thanks for any help
