I would have expected that the "stream" method would become the default. Just a short while ago it was proposed to remove the "fetch" method altogether, and it was only kept because of some niche use cases. I don't think "fetch" is the most safe method, because it requires wal_keep_segments to be configured.
Eh. Yes. That's exactly what this patch does, is it not?
I'd say the main reason fetch was kept around was to support tar file mode, which previously did not support streaming. I don't really see any other usecase where it was better than stream.
