Django partitioning

Django partitioning is a package for Django, which implement PostgreSQL table partitioning on the fly, at the database level. It creates several triggers and functions and inserts them directly into the database. After setup partitioning, record will be inserted into the correct partition, if partition doesn't exist, it will be created for you automatically.

• Django >=1.11 <=5.0
• PostgreSQL >= 8.0

Also, note psycopg2-binary (2.7.5-2.9.9) will be needed as PostgreSQL database adapter.
