================================= PostgreSQL specific model indexes ================================= .. module:: django.contrib.postgres.indexes .. versionadded:: 1.11 The following are PostgreSQL specific :doc:`indexes </ref/models/indexes>` available from the ``django.contrib.postgres.indexes`` module. ``BrinIndex`` ============= .. class:: BrinIndex(fields=[], name=None, pages_per_range=None) Creates a `BRIN index <https://www.postgresql.org/docs/current/static/brin-intro.html>`_. The ``pages_per_range`` argument takes a positive integer. ``GinIndex`` ============ .. class:: GinIndex() Creates a `gin index <https://www.postgresql.org/docs/current/static/gin.html>`_. To use this index on data types not in the `built-in operator classes <https://www.postgresql.org/docs/current/static/gin-builtin-opclasses.html>`_, you need to activate the `btree_gin extension <https://www.postgresql.org/docs/current/static/btree-gin.html>`_ on PostgreSQL. You can install it using the :class:`~django.contrib.postgres.operations.BtreeGinExtension` migration operation.
