If you're saying that single-master logical replication isn't useful, I disagree. Of course, having both single-master and multi-master replication together is even more useful. But I think getting even single-master logical replication working well in a single release cycle is going to be a job and a half. Thinking that we're going to get MMR in one release is not realistic. The only way to make it realistic is to put MMR ahead of every other goal that people have for logical replication, including robustness and stability. It's entirely premature to be designing features for MMR when we don't even have the design for SMR nailed down yet. And that's even assuming we EVER want MMR in core, which has not even really been argued, let alone agreed. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
