Any improvements for Streaming Replication are welcome.
So, I agree with your idea in general, and have some comments.
There seem to be many TODO items on your idea. Since it's
almost impossible to cope with all at the same time, I think
that you should break down your idea to some self-contained
- WAL sending/receiving hook for WAL filtering.
This feature is also useful for compression of WAL data
- Recovery per database-object (e.g., database, table...).
This feature is also useful for partial recovery when one
part of a database is damaged.
- Automatic online-backup from the primary to the standby.
This is already pointed by Heikki.
Let's go forward in stages.
