You could listen to an underlying logical decoding stream, but it might be a bit fiddly and complex for your needs. Ideally we'd be able to fire triggers in BDR, but that's not implemented or on the current roadmap and there's no funded work on it at this point. There's some work to support it in pglogical though. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
