+many. Although I'm not sure if we managed to find a safe relation swap. If not: How about adding ALTER INDEX ... SWAP which requires an exclusive lock but is fast and O(1)? Than all indexes can be created concurrently, swapped in a very short xact, and then dropped concurrently? 95% of all users would be happy with that and the remaining 5 would still be in a better position than today where the catalog needs to be hacked for that (fkeys, pkeys et al). --- Please excuse brevity and formatting - I am writing this on my mobile phone. -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
