I guess we can make a better assessment by seeing what it would take. I'm afraid it will turn out to be really ugly. Now, there's some desire to have unlogged indexes on logged tables; I guess if we have that, then eventually there will also be a desire to swap individual indexes from logged to unlogged. Perhaps whatever fix we come up with here would pave the road for that future feature. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
