pg_repack is a PostgreSQL extension which lets you remove bloat from tables and indexes, and optionally restore the physical order of clustered indexes. Unlike CLUSTER and VACUUM FULL it works online, without holding an exclusive lock on the processed tables during processing. pg_repack is efficient to boot, with performance comparable to using CLUSTER directly.
Please check the documentation (in the doc directory or online) for installation and usage instructions.
What about pg_reorg?
pg_repack is a fork of the pg_reorg project, which has proven hugely successful. Unfortunately development appears to have stopped after the release of the version 1.1.7, around August 2011.
pg_repack 1.1.8 was released as a drop-in replacement for pg_reorg, addressing some of the shortcomings of the last pg_reorg version (such as support for PostgreSQL 9.2 and EXTENSION packaging) and known bugs. Shortly after the first pg_repack release, pg_reorg 1.1.8 was released too, merging all the pg_repack changes. Version 1.1.8 is the last pg_reorg release at the time of writing.
pg_repack 1.2 is a new development line based on the original pg_reorg codebase and offering new features. Its behaviour may be different from the 1.1.x release so it shouldn't be considered a drop-in replacement: you are advised to check the documentation before upgrading from previous versions.
