I've changed that and added paragraph about multi-master replication
explicitly. Additionally, I'm now mentioning the alternative terms
master-slave as well as primary and secondary.
A paragraph about failover and standby has been added. And the eager vs
lazy text has been made clearer (hopefully).
Other additions: shared-disk vs shared-nothing, vertical and horizontal
partitioning and a rant about 'grids'.
Thank you for your inputs.
Regards
Markus
