That isn't going to happen, because of the way streaming replication is implemented. Besides, you haven't even described what interface such a feature would actually have. How would it know which tuples to replicate? Is that really a more sensible interface than just being able to selectively replicate a subset of tables? Consider a trigger-based replication system like Slony or Londiste, which allow asynchronous replication at table granularity. -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
