You mean, if we detect abort in the write callback, set something in the context which will make all the future writes noop until it's reset again after we yield back to the logical decoding? That's not the most beautiful design I've seen, but I'd be okay with that, it seems like it would solve all the issues we have with this. -- Petr Jelinek http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
