## What it is
pg_partman is a PostgreSQL extension that creates and manages time-based and number-based table partition sets using built-in declarative partitioning. It automates partition maintenance such as creating new child tables and dropping old ones via retention policies, including a background worker that runs maintenance without an external scheduler.

## Use cases
- automatically create and drop time-based partitions in postgres
- manage partition retention policies for large tables
- convert an existing table into a partitioned table
- run partition maintenance without cron using a background worker
- set up numeric range partitioning for postgres tables
- migrate legacy trigger-based partitioning to declarative partitioning

## When to choose
- you need automated creation and retirement of postgres table partitions over time
- you want declarative partitioning with retention policies and minimal external scheduling
- you are migrating large existing tables to partitioned layouts in postgres

## When to avoid
- you use a database other than postgresql
- you need trigger-based (pre-10) partitioning methods, which are deprecated
- your tables are small enough that partitioning adds unnecessary complexity

## Facets
- artifact type: library
