No, and while people used to, we're past that now. However, infrastructure improvements to make out-of-tree logical replication that we can get into user hands *now* rather than two+ years from now have been getting knocked back because there's no in-tree user, and tools like pglogical dismissed as irrelevant. Once we have logical replication in core hopefully we can start making infrastructure progress again as well. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
