Upcoming Django 1.2 & PostgreSQL 9.0

http://docs.djangoproject.com/en/dev/topics/db/multi-db/#topics-db-multi-db
Django 1.2 新功能: Multiple databases

PostgreSQL 9.0 新功能 Hot Standby跟Streaming Replication

http://wiki.postgresql.org/wiki/Streaming_Replication

http://developer.postgresql.org/pgdocs/postgres/hot-standby.html

還沒空試, 不過結合這幾個新功能的話似乎可以有效的分散django資料庫端的read/write, 將write-only database server上的WAL(write-ahead log) 即時streaming到read-only database server上的hot standby database, 感覺好像不錯~~
