|
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 the last version of pg_reorg was 1.1.7, released
|
|
in Aug. 2011, and development of the project has stagnated since then. The
|
|
first release of pg_repack contains many key improvements which have been
|
|
missing from pg_reorg (e.g. support for PostgreSQL 9.2, and EXTENSION
|
|
packaging).
|
|
|
|
In an effort to make the transition for existing pg_reorg users simple, and
|
|
facilitate a possible merge back with pg_reorg, we are releasing
|
|
pg_repack 1.1.8 as a drop-in replacement for pg_reorg, addressing the
|
|
pg_reorg 1.1.7 bugs and shortcomings. We are also developing new features
|
|
to be released in an upcoming 1.2 version. pg_repack may be an interim
|
|
solution, should the pg_reorg project come back to life.
|
|
|
|
In the meantime, we thank the original pg_reorg authors for the quality code
|
|
they have released to the community, wish them good luck, and hope to
|
|
collaborate further in the future.
