- ``django.contrib.postgres``
- ===========================
- .. module:: django.contrib.postgres
- :synopsis: PostgreSQL-specific fields and features
- PostgreSQL has a number of features which are not shared by the other databases
- Django supports. This optional module contains model fields and form fields for
- a number of PostgreSQL specific data types.
- Psycopg2 2.5 or higher is required.
- .. note::
- Django is, and will continue to be, a database-agnostic web framework. We
- would encourage those writing reusable applications for the Django
- community to write database-agnostic code where practical. However, we
- recognize that real world projects written using Django need not be
- database-agnostic. In fact, once a project reaches a given size changing
- the underlying data store is already a significant challenge and is likely
- to require changing the code base in some ways to handle differences
- between the data stores.
- Django provides support for a number of data types which will
- only work with PostgreSQL. There is no fundamental reason why (for example)
- a ``contrib.mysql`` module does not exist, except that PostgreSQL has the
- richest feature set of the supported databases so its users have the most
- to gain.
