Description
According to stack overflow, unlogged tables are the way to go for testing speed. See http://stackoverflow.com/questions/9407442/optimise-postgresql-for-fast-testing/9407940#9407940 for example.
As part of another, now rejected ticket, somebody wrote support for unlogged tables:
https://github.com/aptivate/django/commits/ticket_19891 first commit: https://github.com/aptivate/django/commit/657a1fee1ad3899f1254a971f32a6cea7b11c0a3
Support for unlogged tables for testing would be really helpful for having tests run faster.

Replying to freyley:

I've tried this a while ago (by hacking Django's internals) and there was not much gain from it.
But I was using most(?) of https://www.postgresql.org/docs/current/static/non-durability.html already.

A different use for UNLOGGED tables could be for the database cache backend: https://martinheinz.dev/blog/105. Would it be an option to allow specifying an --unlogged
parameter for the createcachetable
command to create an UNLOGGED table for the database cache?

Some discussion here. Looks like the Postgresql-specific option may be a problem, and the UNLOGGED feature may not give much performance improvement for caches.
According to discussion on django-developers unlogged tables actually decreased performance for Django's own test suite.
