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 was initially 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.
pg_repack 1.2 introduces further new features (parallel index builds, ability to rebuild only indexes) and bugfixes. In some cases 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.
