If you run 'git show --stat b89e151054a05f0f6d356ca52e3b725dd0505e53',
you will see that it includes a test_decoding module (which is a
sample logical decoding output plugin) and a tremendous pile of
changes to src/backend/replication/logical (which is the core logical
decoding infrastructure). The latter is a larger volume of changes
than the former. It would perhaps be fair to describe test_decoding
as a proof-of-concept, but it is not fair or correct to describe the
core infrastructure that way. Anyway, they're separate things.
