Adds a reasonably feature complete implementation of full text search using the built in PostgreSQL engine. It uses public APIs from Expression and Lookup. With thanks to Tim Graham, Simon Charettes, Josh Smeaton, Mikey Ariel and many others for their advice and review. Particular thanks also go to the supporters of the contrib.postgres kickstarter.

.. 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, though we highly recommend using the latest
|
|
release. Some fields require higher versions.
|
|
|
|
.. 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.
