I have a few questions about this:
1. Why is this in src/bin/pg_basebackup? As far as I can see, this has
nothing to do with taking base backups. I guess one could say the same
thing about pg_receivexlog, but that one is at least somewhat related to
a physical base backup, and shares code with pg_basebackup.
2. What is this good for? I would read the docs, but:
3. There are no docs.
It's a bit hard to be sure without understanding the purpose of this,
but I think this belongs in contrib, as an example of how to write a
logical decoding client. If it's only useful for "testing and debugging,
possibly more" as the commit message says, I don't think this should be
installed by default by "make install".
