I like the feature you are proposing, but I don't think that we should block Alexander from moving forward with a more-extensible WAL format. I believe that's a general need even if we get the features you're proposing, which would reduce the need for it. After all, if somebody builds an out-of-core index AM, ignoring WAL-logging, and then decides that it works well enough that they want to add WAL-logging, I think we should make that possible without requiring them to move the whole thing in-core. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
