|
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.
