I think the "users get control" montra could be a theme for this
release;  I think it would apply to all of these:

    * Unlogged tables to better handle some NoSQL workloads
    * Synchronous replication for greater reliability
    * SQL/MED (Management of External Data) (flat files, other databases)
    * Per-column collation support
    * Security Label, including SE-Linux integration
    * True serializable isolation with predicate locking (already had snapshot isolation)
