MySQL Cluster is a specific product. It is not just mysql databases
lumped together to make a big mysql DB. It is a memory-based
database that requires at least 2 machines to run, and is not
usefully redundant and distributed until you have many machines. The
telco's use it for their logging and switching infrastructure where
you need 100% uptime and wicked fast response (thus memory based.)
And you'll note it was developed by Ericsson...
There is no equivalent in Postgres.
There are several replication choices for Postgres. Google will find
them for you, or just look on the postgres.org pages for the list.
We use slony1 and it works very well for our need.
