Scalable open source PostgreSQL-based database cluster

Postgres-XL is an open source project to provide both write-scalability and massively parallel processing transparently to PostgreSQL. It is a collection of tightly coupled database components which can be installed on more than one system or virtual machine.

Write-scalable means Postgres-XL can be configured with as many database servers as you want and handle many more writes updating SQL statements than a single standalone database server could otherwise do. You can have more than one database server that provides a single database view. Any database update from any database server is immediately visible to any other transactions running on different servers. Transparent means you do not necessarily need to worry about how your data is stored in more than one database servers internally.
