## What it is
pg_repack is a PostgreSQL extension and CLI tool that removes bloat from tables and indexes with minimal locking, as an online alternative to CLUSTER and VACUUM FULL. It is a maintained fork of pg_reorg, supporting extension packaging and parallel index builds.

## Use cases
- remove bloat from postgres tables without downtime
- rebuild bloated indexes online
- reorganize tables to restore clustered index physical order
- replace vacuum full with a non-blocking alternative
- defragment postgres tables in production

## When to avoid
- you use a database other than PostgreSQL
- you need to repack tables without the disk space for a temporary copy
- you require a tool with a graphical interface
