pg_repack -- Reorganize tables in PostgreSQL databases with minimal locks ========================================================================= - Homepage: http://reorg.github.com/pg_repack - Download: http://pgxn.org/dist/pg_repack/ - Development: https://github.com/reorg/pg_repack - Bug Report: https://github.com/reorg/pg_repack/issues - Mailing List: http://pgfoundry.org/mailman/listinfo/reorg-general 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. .. _pg_repack: http://reorg.github.com/pg_repack .. _CLUSTER: http://www.postgresql.org/docs/current/static/sql-cluster.html .. _VACUUM FULL: VACUUM_ .. _VACUUM: http://www.postgresql.org/docs/current/static/sql-vacuum.html .. _online: pg_repack_ 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. .. __: pg_repack_ .. _pg_reorg: http://reorg.projects.pgfoundry.org/
