My point here wasn't really about renaming, although I do think renaming is something that should get done. My point was that you were saying we need to mark index pointers as common, pre-warm, and post-warm. But you're pretty much already doing that, I think. I guess you don't have "common", but you do have "pre-warm" and "post-warm". -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
