I'll point out that the simple version, which just checks for hot tables and indexes, would improve estimates greatly and be a LOT less complicated than these proposals. Certainly having some form of block-based or range-based stats would be better, but it also sounds hard enough to maybe never get done. Having user-accessible "hot" stats would also be useful to DBAs. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
