Well, frequently when people discuss ideas on this list, others discuss and provide further ideas to try help to find a working solution, rather than throw every roadblock they can think of (though roadblocks are indeed thrown now and then). If I've taken a long time to find a working solution, maybe it's because I have no shoulders of giants to stand on, and I'm a pretty short guy, so I need to build me a ladder. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
