Postgres-XL is a PostgreSQL-based scale-out cluster that handles both OLTP write intensive workloads as well as OLAP/BI type of workloads thanks to MPP parallelism. Postgres-XL is fully ACID and supports cluster-wide Multi-version Concurrency Control (MVCC) for global consistency and performance. There are commercial companies such as 2ndQuadrant, who provide support and consulting around Postgres-XL. Please visit http://2ndquadrant.com/en/resources/postgres-xl/ for more details.

pg_reorg can re-organize tables on a PostgreSQL database without keeping any locks so that you can retrieve or update rows in tables being reorganized. This module is developed to be a better alternative of CLUSTER and VACUUM FULL. ------- pg_reorg was located in pgfoundry, but has been moved to here temporally. ************************************ 2015.07.03 Now, we are moving to GitHub. http://github.com/ossc-db/pg_reorg ************************************
