Replying late here, but I think with binary replication, we decided
that, assuming you were happy with the features provided, our streaming
binary replication solution was going to be the best and recommended way
of doing it.
I don't think we ever had that feeling with Slony or Londiste in that
there were so many limitations and so many different ways of
implementing logical replication that we never recommended a best way.
So, the question is, do we feel that PgLogical is best and recommended
way to do logical replication. If it is, then having it in core makes
sense.
