PostgreSQL Replication

PostgreSQL takes the replication strategy of MySQL and breaks it into two pieces:

• Streaming Replication
• Log Shipping Replication

While MySQL combines both of those into a single process, PostgreSQL splits them

    // the back and forward buttons navigate through the tabs. Note: this doesn't
    // handle keyboard navigation of the tabs. That's probably OK, since the tabs
    // have special handling for keyboard navigation built in, and back/forward
    // doesn't really make sense in that context.
